Description

  The present invention relates to a body restraint device that can freely open and close a restraint arm, restrains the hands and feet of criminals and thieves, etc., and deprives the body of freedom, prevents resistance and escape, and criminal and thugs It is related with the opening-and-closing body restraint tool which can take a sufficient distance from the life from such as, and the urgent attack to the body, and can protect a body.

  Traditionally, piercing has been used as a crime prevention device or catching device that protects against criminals carrying blades, etc., and when police officers arrest criminals, they are locked using handcuffs Things have been done. In addition to these traditional body restraints, body restraints provided with a locking mechanism to lock the closed state have been proposed so that the open / close part does not open to some extent even if it is not completely closed. Yes.

  As such a body restraint tool, for example, there is an “open / close trap” described in Japanese Patent Application Laid-Open No. 2007-71525, and there is a “body restraint device that can be opened and closed” described in Japanese Patent Application Laid-Open No. 2010-175113. The “open / close trap” and “stabbed openable body restraint device” described in the above publications have a bifurcated opening / closing portion that is kept closed according to the size of the object to be captured, thereby freeing the body. Is configured to take away.

  The "open / close type trap" described in JP-A-2007-71525 discloses that the two arms of an openable / closable gripping part attached to the tip of a slide shaft press the gripping part against a capture object. The slide shaft slides in the direction of the hand, and the two arms close in the direction approaching each other according to the slide, and the slide shaft is configured to be controlled by the stopper means to slide in the tip direction. .

  In addition, in the “body restraint that can be opened and closed” disclosed in Japanese Patent Application Laid-Open No. 2010-175113, a spring for closing the arm of the gripping part is used on the slide shaft, and the gripping part is pressed against the captured object. And the arm can be closed by the biasing force of the spring. Then, a lock part is formed by a rack type engaging part made of a sawtooth projection on the slide shaft, and an engaging part having an engaging piece for engaging with the rack type engaging part. When the state is maintained, the slide shaft is formed so as to slide only in the hand direction.

JP 2007-71525 A JP 2010-175113 A

  The "opening / closing type trap" described in the above publication is one that is closed to surround the body of a thief or the like and takes freedom, and is closed according to the sliding width of the slide shaft, and the appropriate closed state Is held by the stopper means and locked so as not to move in the opening direction. However, since the two arms that restrain the body are closed by pressing the tip of the shaft against the object to be captured, they can easily escape from the restraint before being completely closed. It is reasonable to run away if it is pressed, and it is practically difficult to restrain.

  Moreover, although the stopper means for maintaining the closed state is provided, the arm cannot be opened instantaneously. In order to open the arm of the gripping part from the closed state according to the sliding width of the slide shaft, the arm must be opened by hand while releasing the locked state by the stopper means. In such an operation method, there is a risk that the object to be captured can escape, and there is also a risk of being counterattacked.

  Japanese Patent Application Laid-Open Publication No. 2010-175113 discloses a body restraint tool that can be opened and closed, by operating the opening / closing holding portion without pressing the distal end portion of the slide shaft. Since the sandwiching member can be closed, a thug can be restrained.

  However, in this invention as well, the closed pinching member must be opened by hand while releasing the locked state, similar to the above-mentioned “open / close trap”. In addition, since the operation rod is formed long in order to keep a distance from a thief and avoid danger, it cannot be loaded on a police car and is difficult to carry and store.

  As described above, the conventionally proposed body restraint has a problem that it cannot be immediately handled in the field when it cannot be restrained completely. The present invention solves the above-described problems, and can avoid the danger of the body from a thief or the like, can instantly close the restraining arm without pressing against the object, and can also close the restraint. An object of the present invention is to provide an openable body restraint that can open an arm with one touch. Another object of the present invention is to provide an opening / closing body restraint that is advantageous in storing and transporting an operating rod that can be extended and contracted.

In order to achieve the above object, the present invention is configured as follows. The opening / closing body restraint device according to the present invention is:
Provided with a restraining part at one end of the operation rod, and provided with a slide member, a lock mechanism and a stopper mechanism for opening and closing the restraining part,
The restraining portion includes a pair of restraining arms formed with curved surfaces on the inside, and the inner end of the restraining arm is rotated through a fixing member to the tip of a slide member that is slidably inserted into the operating rod. The shaft is movably mounted and fixed to the distal end of the operation rod, and the swing plate is pivotally mounted between the support member and the restraining arm, which is slidably inserted through the slide member. The restraint arm is formed to be openable and closable,
The lock mechanism includes a key guide that slides inside the operation rod, a ratchet key that is embedded in the key guide so as to be able to move in and out, and a transparent hole that is formed in the center of the ratchet key from a pin hole provided in the shaft core of the key guide. A release pin that enters and exits the hole, and a serrated groove that is formed on the inner surface of the operation rod and engages with the tip of the ratchet key. Attach and attach a spring between the key guide and the operating rod,
The stopper mechanism is composed of a button pin provided in the key guide, a through hole into which the button pin drilled in an operating rod is inserted, and a release plate that pushes down the button pin.
The slide member is inserted into a main tube spring receiver projecting in an operating rod, the rear end portion is fixed to the key guide, and a spring is mounted between the main tube spring receiver and the key guide. To do.

The operation rod and the slide member can be extended and contracted. In order to make the operation rod and the slide member extendable and retractable, the operation rod may be formed by the front end tube and the original tube into which the front end tube is inserted, and the slide member may be formed by the slide tube and the slide bar inserted into the slide tube. .
In order to make the operating rod and the slide member extendable and retractable, the operating rod consists of a front end tube and a main tube into which the front end tube is inserted, and a fixing button pin is provided at the rear end portion of the front end tube. A through hole is formed in each of the front end portion and the rear end portion to fit the fixing button pin when extending and contracting, and the slide member includes a slide tube and a slide bar that is slidably inserted into the slide tube. The spring bar is formed on the outer peripheral side of the slide tube on the inner surface of the tip tube so that the locking piece at the tip of the slide bar is locked to the locking plate provided at the bottom of the slide tube when extended. It may be formed by attaching a pressing spring that is locked to the tip and biases the slide tube in the distal direction.

  It is preferable to provide a non-returning roller that rotates only inward and does not rotate outward at the tip of the restraining arm. Moreover, it is preferable that the tip of the ratchet key and the serrated groove in the locking mechanism are formed of a vertical surface and an inclined surface, and the inclined surface is inclined toward the inner side of the proximal side.

  The openable / closable body restraint tool of the present invention can be operated with one hand, and the restraint arm portion can be opened and closed with one touch. Therefore, when closing the restraint arm, it can be closed instantly when it enters the restraint arm without being pressed against a thug. In addition, since the guide roller that rotates only inside is attached to the tip of the restraining arm, it can be easily restrained by the synergistic action with the guide roller by just entering the restraining arm. is there. Further, when opening the restraining arm part, it is only necessary to push in the hand side of the operating rod, and it may be pushed against the ground while being held with one hand or pushed with the other hand.

  Further, since the closed state of the restraining arm portion can be maintained until the lock is released, the freedom of action can be continuously taken away like a handcuff. In addition, when the operation rod is telescopic, it can be stored in a car such as a police car because it does not become bulky by shortening, and it can also be used for defense against attacks like a baton. In addition, since it can be operated with one hand, it is possible to restrain the body of a thief who resists violently while aiming for safety.

It is the top view which sectioned a part of the state where the restraint arm part of the body restraint tool concerning a 1st embodiment of this invention opened. It is the enlarged view to which a part of FIG. 1 was expanded. Similarly, it is the top view which sectioned a part of the state where the restraint arm part of the body restraint tool closed. It is the enlarged view to which a part of FIG. 3 was expanded. FIG. 6 is a plan view of a part of the state in which the operating rod is shortened and the restraining arm is closed. It is sectional drawing of other embodiment which shows the fixation structure of the front-end | tip cylinder and the original cylinder which form an operating rod. It is the top view which sectioned a part of the state where the restraint arm of the body restraint tool concerning a 2nd embodiment opened. Similarly, it is a top view which shows the restraint arm part of the open state.

  Next, an embodiment of an openable body restraint device according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a part of a first embodiment of an openable / closable body restraint device (hereinafter simply referred to as a body restraint device) according to the present invention, and FIG. 2 is an enlarged view of a part of an operating rod. It is.

  The illustrated body restraint tool 1 includes a restraint portion 2, an operating rod 3 that fixes and operates the restraint portion 2, a slide member 4 that opens and closes the restraint portion 2, and a slide member that slides when the restraint arm is closed. The lock mechanism 5 is configured to be locked, and the stopper mechanism 6 is configured to hold the restraining arm of the restraining portion 2 in an open state.

  More specifically, the restraining portion 2 is fixed to a pair of independent restraining arms 11 and 11 that can be opened and closed, a fixing member 12 disposed between the restraining arms 11 and 11, and a distal end of an operating rod. The support member 13 is slidably inserted through the slide member 4 and the swing plate 14 is rotatably fixed between the inner ends of the restraining arms 11 and 11 and the support member 13.

  The restraint arms 11 and 11 are formed in a substantially hook shape in a planar shape, and curved surfaces 11a and 11a are formed on the inner surface so that a body such as a thief, particularly a hand or a leg, can be restrained. Yes. The restraining arms 11 and 11 are plate-like bodies, and are provided with a plurality of through holes 11b for weight reduction, and guide rollers 20 and 10 are used as guide members for facilitating insertion of limbs at the distal ends. 20 is attached. The guide rollers 20, 20 are preferably non-returning rollers that rotate only inward and do not rotate outward. Since the guide rollers 20 and 20 rotate only inward, when the restraining arms 11 and 11 are closed, the limbs to be sandwiched are guided inward and can be sandwiched more effectively.

  The guide rollers 20 and 20 guide the limbs to be sandwiched inside the restraining arms 11 and 11, and are attached to the distal ends of the restraining arms 11 and 11 in opposite directions. The guide rollers 20 and 20 can be omitted, and can be guide members having other configurations. For example, a guide plate that opens outward may be attached to the distal end portions of the restraining arms 11, 11, or the distal end portion may simply be a tapered surface.

  Further, the restraining arms 11 and 11 will be described in detail. The restraining arms 11 and 11 may be formed with bent portions bent at opposite sides in the intermediate portion so that the tip portions can intersect when closed. preferable. By forming the bent portion, as shown in FIG. 3, the tip portion of the bent portion intersects with each other on the side in the vertical direction. Since the restraining arms 11 and 11 have the curved surfaces 11a and 11a and are formed so as to be able to intersect with each other by forming a bent portion, the gap formed by the curved surface is gradually reduced when closed. Can cope with the thickness of the limbs.

  The inner ends 11c of the restraining arms 11 and 11 are pivotally attached to the fixing member 12 by a shaft 15, and the fixing member 12 is inserted into the operating rod 3 so as to be slidable. It is fixed to the part. Further, a swing plate 14 is pivotally attached to the outer corners 11 d and 11 d of the restraining arms 11 and 11 by a shaft 17. One end of the swing plate 14 is pivotally attached to the support member 13 by a shaft 16, and the other end of the swing plate 14 is pivoted to the outer corners 11 d and 11 d of the restraining arms 11 and 11 by a shaft 17. It is worn.

  Since the support member 13 is fixed to the tip of the operating rod 3 and the slide member 4 is slidably inserted, when the slide member 4 is retracted toward the hand side, the fixing member 12 is also retracted simultaneously. The restraining arms 11 and 11 side of the sliding plate 14 opens outward. Further, when the slide member 4 is retracted toward the hand side, the inner end of the restraining arms 11 and 11 is pushed down while the swing plate 14 is opened, so that the distal end side of the restraining arms 11 and 11 approaches the shaft 15 as a center. (See FIG. 3). Although the restraining arms 11 and 11 are closed, a gap is formed by the curved surfaces 11a and 11a, and a hand or a leg is sandwiched in the gap.

  On the contrary, when the slide member 4 advances in the distal direction, the fixing member 12 also advances at the same time, and the restraining arms 11 and 11 side of the peristaltic plate 14 closes inward. Further, when the slide member 4 moves forward, the inner ends of the restraining arms 11 and 11 are pulled up while the swing plate 14 is closed, and the leading ends of the restraining arms 11 and 11 are opened around the shaft 15. (See FIG. 1).

  Next, the operation rod 3 will be described with reference to FIGS. 1 and 3 are assembled views when the operating rod 3 is extended. The operating rod 3 is formed to be extendable and contractible by a tip tube 31 and a base tube 32 into which the tip tube 31 is inserted. A fixing button pin 33 that can be moved in and out by a spring is provided at the proximal end of the distal end tube 31. When the operating rod is extended on the distal end side of the original tube 32, the button pin 33 is A through hole 34a into which the button pin 33 is fitted when the operating hole is contracted and the through hole 34 to be fitted is formed.

  The fixing button pin 33 provided on the distal end cylinder 31 is fitted into the through hole 34 of the original cylinder 32 to maintain the extended state. When the operating rod 3 is reduced, the distal end tube 31 can be inserted into the original tube 32 by pressing the fixing button 33 to release the fitting with the through hole 34. When the distal end tube 31 is inserted into the original tube 32 and the fixing button pin 33 is fitted into the through hole 34a, the reduced state is maintained.

  The slide member 4 is formed to be extendable and retractable corresponding to the operation rod 3 and includes a slide bar 42 inserted into the slide tube 41. The slide tube 41 is slidably inserted into the distal end cylinder 31, and a fixing member 12 that forms the restraint portion 2 is fixed to the distal end. The slide tube 41 and the slide bar 42 are formed in a plunger structure. The slide bar 42 is inserted through a through hole of a locking plate 43 provided at the bottom of the slide tube 41, and a locking piece 44 provided at the tip of the slide bar 42 is connected to the locking plate 43 from the inside of the slide tube 41. By locking, it is prevented from coming off.

  The slide tube 41 includes a tip support portion 41a inserted into the support member 13 and a pipe portion 41b into which the slide bar 42 is inserted, and a pressing spring 44 is mounted on the outer periphery of the pipe portion 41b. The pressing spring 44 is mounted between a spring receiver 45 provided on the inner surface of the tip tube 31 and a tip support portion 41a, and biases the slide tube 41 by the tip support portion 41a and the pipe portion 41b in the tip direction. ing.

  Since the slide tube 41 is urged in the distal direction by the pressing spring 44, the restraining arms 11 and 11 are always opened when the pressing spring 44 is extended. When the slide tube 41 slides in the hand direction, the pressing spring 44 is compressed and the restraining arms 11 and 11 are closed.

  The rear end (hand side) of the slide bar 41 is inserted through a later-described main cylinder spring receiver, and the rear end is fixed to a slidable key guide. When the slide member is reduced, the slide bar may be pushed into the slide tube 41.

  Next, the lock mechanism 5 and the stopper mechanism 6 will be described with reference to FIGS. First, the lock mechanism 5 will be described. The lock mechanism 5 includes a key guide 51 that slides in the main cylinder 32, a ratchet key 52 that is inserted into the key guide 51 to be movable up and down, and a through hole 52 a that is formed in the center of the ratchet key 52. The release pin 53 is formed, and the sawtooth groove 32a is formed on the inner surface of the original cylinder 32 in the range in which the ratchet key 52 slides.

  More specifically, the sawtooth groove 32a is formed by continuously forming independent grooves of a vertical surface and an inclined surface. The inclined surface is inclined toward the inside of the hand side. The slide bar 42 is fixed to the tip of the key guide 51, and the slide bar 42 slides integrally with the key guide 51. The ratchet key 52 is provided with a through hole 52a into which the release pin 53 is inserted at the center, the proximal side surface is formed as a tapered surface 52b, and the tip is formed at an acute angle.

The ratchet key 52 is fitted in a mounting hole 54 formed in the key guide 51 in the radial direction, and is urged outward by a spring 55. Accordingly, since the sawtooth groove 32a and the ratchet key 52 are each formed with an inclined surface, the ratchet key 52 slides in the hand direction but also slides in the tip direction even in the engaged state. It is prevented. Thus, when the key guide 51 is engaged with the serrated groove 32a, the key guide 51 slides only in the proximal direction, and the restraining arms 11, 11 are locked in the closed state.

  A pin hole 56 for inserting the tip of the release pin 53 is formed in the shaft core of the key guide 51. The pin hole 56 is opened on the hand side and provided through the attachment hole 54. When the ratchet key 52 is urged outward by the spring 55 and the release pin 53 is inserted, the ratchet key 52 is pushed down and the engagement between the serrated groove 32a and the ratchet key 52 is released. The serrated groove 32a and the ratchet key 52 are engaged, and the through hole 52a and the pin hole 56 of the ratchet key 52 are formed so that the positions of the holes are partially shifted.

  The front end portion of the release pin 53 is tapered, and the rear end portion is connected to the operation unit 60 via a sliding pin holder 57. The operation portion 60 includes a slide portion 62 and a grip portion 63 that are slidably inserted into a fixed ring 61 fixed to the rear end surface of the main tube 32. Therefore, the release pin 53, the pin holder 57, and the slide portion 62 slide together.

  A pressing spring 64 is provided between the key guide 51 and the pin holder 57. When the release pin 53 is pulled out from the through hole 52 a of the ratchet key 52, a predetermined gap is maintained between the key guide 51 and the pin holder 57 by the pressing spring 64. When the retracting release pin 53 moves forward and the tip portion is inserted into the through hole 52 a of the ratchet key 52, the ratchet key 52 is pushed down against the spring 55. When the ratchet key 52 is pushed down, the engagement state with the serrated groove 32a is released, so that the key guide 51 can slide in the distal direction.

  The stopper mechanism 6 is an operation mechanism for holding the restraining arms 11 and 11 in an opened state and closing them instantaneously. The stopper mechanism 6 is formed by a button pin 65 embedded in the key guide 51, a release plate 66, and a pressing spring 67. The button pin 65 is fitted into a mounting hole 68 provided in the key guide 51 in the radial direction so that a head is exposed from a through hole 32 b provided in the base tube 32 by a spring 67 provided at the bottom. Is formed.

  The release plate 66 has flexibility, and a protrusion 66a that abuts the button pin 65 is provided on the lower surface thereof. Therefore, when the release plate 66 is pushed down, the projection 66a pushes the head of the button pin 65 down to the inner surface of the main tube 32.

  Further, a pressing spring 70 is provided between the main cylinder spring receiver 69 and the key guide 51. The main cylinder spring receiver 69 is fixed inside the main cylinder 32, and the slide bar 42 is slidably inserted therethrough. Since one end of the pressing spring 70 is fixed by the main cylinder spring receiver 69, the key guide 51 and the slide bar 42 are urged toward the proximal side.

  Next, a method of using the body restraint tool 1 according to the above configuration will be described. When the restraining arms 11 and 11 are opened, the grip part 63 of the operation part 60 is pushed in and the slide part 62 is slid in the distal direction. In order to slide the slide part 62 in the distal direction, the grip part 63 may be pushed by hand or may be pushed against the ground.

  When the slide portion 62 is slid, first, the pressing spring 64 is compressed and the tip of the release pin 53 is inserted into the through hole 52 a of the ratchet key 52. Further, when the release pin 53 is inserted into the through hole 52a as it is, the ratchet key 52 is pushed down to compress the pressing spring 70 and the engagement between the tip of the ratchet key 52 and the sawtooth groove 32a is released. Therefore, the key guide 51 can be easily slid in the distal direction.

  When the key guide 51 slides and advances in the distal direction, the slide bar 42 is inserted into the slide tube 41 while compressing the pressing spring 70. When the slide bar 42 is inserted into the slide tube 41, the slide tube 41 is pulled toward the hand side and the compression of the pressing spring 44 is released, so that the fixing member 12 is protruded by the urging force of the pressing spring 44. By the protrusion of the fixing member 12, the restraining arms 11 and 11 are opened so as to be separated from the guide roller 20 side (see FIG. 1).

  At the same time as the distal ends of the restraining arms 11, 11 are opened, the heads of the button pins 65 provided in the key guide 51 are fitted into the through holes 32 b formed in the base tube 32, and the fixing portion 12 is pushed in. Also, sliding of the slide member 4 in the hand direction is prevented (see FIGS. 1 and 2).

  The head portion of the button pin 65 is fitted into the through hole 32b of the main tube 32 to prevent the key guide 51 from moving forward, and the operation portion 60 is prevented from being pushed in. When the pressing of the operation unit 60 is stopped, the slide member 62 is pushed back together with the pin holder 57 by the pressing spring 64, and the release pin 53 is pulled out from the through hole 52 a of the ratchet key 52.

  To close the restraining arms 11, 11, it is only necessary to press the release plate 66. When the release plate 66 is pressed, the head portion of the button pin 65 is pushed into the inner surface side of the main tube 32 by the protrusion 66a on the lower surface, and the engagement state with the through hole 32b is released. As a result, the key guide 51 is moved backward toward the hand side.

  When the key guide 51 is retracted, the release pin 53 is inserted into the through hole 52 a of the ratchet key 52 while compressing the pressing spring 64. When the release pin 53 is inserted into the through hole 52a, the engagement between the ratchet key 52 and the sawtooth groove 32a is released, so that the key guide 51 is retracted at a stroke.

  When the key guide 51 is retracted, the slide tube 41 is simultaneously pulled by the slide bar 42, so that the pressing spring 44 is compressed and the slide member 4 is also retracted, and the restraining arms 11, 11 are instantaneously closed. When the restraining arms 11 and 11 are closed and the retraction of the key guide 51 is stopped, the operation portion 60 is further pushed out to the hand side by the pressing spring 64, and the release pin 53 is pulled out from the through hole 52a of the ratchet key 52, The engagement between the ratchet key 52 and the sawtooth groove 32a is locked. When the engagement between the ratchet key 52 and the sawtooth groove 32a is locked, the slide member 4 does not slide in the distal direction.

  As described above, the body restraint tool 1 can be closed at once by simply pressing the release plate 66 at the moment of entering the restraint arms 11, 11 without pressing the fixing member 12 against a thief or the like. When the restraining arms 11 and 11 are closed, a gangster or the like can be called into the restraining arms 11 and 11 in combination with the guide roller 20 that rotates only in the inner direction.

  When the restraining arms 11 and 11 are locked in the closed state, they are not released unless the operating portion 60 is pushed in, and the grip portion 63 is provided on the rear end side of the operating rod farthest from the restraining arms 11 and 11. Therefore, a thief or the like cannot push the grip 63 to release the lock.

  Note that, when the restraining arms 11 and 11 are closed, if the fixing member 12 is pressed, the sliding member 4 and the key guide 51 are further slid to the proximal side, and the gap inside the restraining arms 11 and 11 can be reduced. It can be restrained reliably.

  In addition, in the above embodiment, the restraining arms 11 and 11 are configured to intersect and close by forming the bent portion, but may be simply abutted and brought into contact with each other without being intersected, or may be configured to approach each other. In addition, the shape of the restraining arms 11 and 11 may be a shape having a gap on the inner side when sandwiched, and may be formed in a substantially L shape in addition to a curved shape as shown in FIG. It is not particularly limited.

  Next, in order to reduce the operating rod 3, it is only necessary to push the fixing pin 33 to release the engagement with the through hole 34 and insert the distal end tube 31 into the original tube 32. At the same time, the slide bar 42 of the slide member 4 is inserted into the slide tube 41. When the fixing button pin 33 is fitted into the through hole 34a formed in the original cylinder, the reduced state is maintained. At this time, since the compression of the pressing spring 44 is released, the restraining arms 11 and 11 are opened by the urging force of the pressing spring 44 (see FIG. 3).

  FIG. 6 shows another assembly structure of the operating rod 3, which is fixed by screwing the socket 36 attached to the tip tube 31 and the main tube 32. The bottom portion 36a of the socket 36 is engaged with a locking piece 37 projecting from the outer surface of the tip tube 31, and the female screw 36b engraved on the inner surface is screwed with the male screw 31b engraved on the outer surface of the main tube 32. Fixed by. When the socket 36 is removed from the original cylinder 32, the screwing of the female screw 36b and the male screw 31b is loosened, and the socket 36 is moved in the distal direction of the distal end cylinder 31.

  Next, based on FIG.7 and FIG.8, the body restraint tool 1A of 2nd Embodiment of this invention is demonstrated. The operating rod 3A according to the second embodiment is different from the first embodiment in that the tip tube and the base tube are integrally formed and do not expand and contract, and the pressing spring in the tip tube is omitted. . Accordingly, only different configurations will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted.

  The restraining arms 11 </ b> A and 11 </ b> A constituting the restraining portion 2 </ b> A are formed by bending a rod-like body, and are attached to the fixing member 12 and the swinging plate 14 via the fixing plate 15. A guide roller 20A that rotates only in the inward direction is attached to the distal ends of the restraining arms 11A and 11A. The guide roller 20A has a through hole 21 for weight reduction.

  In this embodiment, the pressing spring provided in the distal end cylinder for expanding the restraining arms 11A and 11A is omitted, but the open state is maintained by fitting the button pin 65 into the through hole 32b of the original cylinder 32. Has been. When the restraining arms 11A and 11A are formed of rod-like bodies as in this embodiment, some flexibility can be provided. By having flexibility, it can be deformed according to the movement of a thief or the like, so that the thief or the like can be restrained without hurting.
