The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIGS. 1 to 3, the present invention provides a grip 10 for a restrictively sliding sleeve on a body portion 22 of a body 20 and rotatable relative to the body portion 22. The body portion 22 of the body 20 is provided At least one annular groove 24, more specifically, the body portion 22 of the body 20 is provided with a four-ring type groove 24, but two, three or more ring-shaped grooves may be provided. The grip 10 includes a first sleeve 12, at least one clip 14, a second sleeve 16, and an elastic member 18.

The first set 12 is generally tubular and is provided with at least one perforation 122. More specifically, the first set 12 is provided with two opposing perforations 122, but only one, three or more perforations may be provided. In the case of a plurality of perforations 122, the perforations 122 are preferably, but not limited to, equidistantly disposed in the first set 12. Each of the perforations 122 is located in one of the inner surfaces of the first set 12 and has an opening that is smaller than one of the outer surfaces of the outer surface of the first set 12.

In this embodiment, the grip 10 includes two latching members 14, each of the latching members 14 is received in the through hole 122. Preferably, the latching members 14 are spherical bodies such as balls, steel balls or the like. The structure, and the number thereof, is equal to the number of such perforations 122. The maximum outer diameter of the card member 14 is smaller than the opening outside the perforation 122 and larger than the inner opening of the perforation 122. Such a portion of the card member 14 can enter the interior of the first sleeve 12 from the inner opening, but does not completely pass through the inner portion. open mouth.

The second set 16 is movably sleeved relative to the first set 12 to the first set 12, and the clips 14 are abutted against the second set 16 to controlably engage a portion of the annular groove 24, to snap the grip 10 and the body 20 without any relative sliding or separation. In this embodiment, the second set 16 includes a ring member 162 and a cylindrical member 164. The ring member 162 is detachably fixed to a top end of the first set 12, and the cylindrical member 164 is slidably disposed on the first set The ring member 162 is between the first set 12. Furthermore, the inner ring surface of the ring member 162 is internally threaded, and the top end of the first sleeve 12 is provided with an external thread, and the ring member 162 and the first sleeve 12 are transmitted through the internal thread and the external thread. Screwed to fix. However, the manner in which the ring member 162 is combined with the first sleeve 12 is not limited to the screwing manner.

In this embodiment, the inner wall of the tubular member 164 of the second set 16 is formed with an adjacent annular protrusion 166 and a ring recess 168, and the tubular member 164 of the second set 16 is adjacent to the first set 12 Move between the restricted position and a released position. When the tubular member 164 of the second set 16 is in the restricted position, the annular protrusion 166 is engaged with the card member 14 to partially engage the annular groove 24; when the tubular member of the second set 16 is When the 164 is in the release position, the ring recess 168 is inserted into the card member 14 relative to the card members 14 so that the card members 14 do not get caught in the annular groove 24.

With further reference to FIG. 4 , the elastic member 18 is sleeved on the first sleeve 12 and is elastically abutted against the first sleeve 12 and the second sleeve 16 , more clearly The elastic member 18 is elastically engaged between the tubular member 164 and the first set 12. In this embodiment, the elastic member 18 is a coil spring, and at least one end of the coil spring has a smaller helical pitch than the intermediate portion, whereby the coil spring can have fewer spiral turns, that is, The compression has a smaller length, which reduces the material used for the coil spring and the grip 10 can be made to have a smaller overall length. It can be understood that, in another preferred embodiment, each spiral pitch of the coil spring can be smaller than a width of the card member 14 in a length direction of the first sleeve 12 (for example, a diameter of a sphere). Thus, regardless of the position of the coil spring relative to the first sleeve 12, any two adjacent spiral segments of the coil spring can abut against the card member 14, preventing the card member 14 from being in the second portion. The sleeve 16 is disposed in the first set 12 and is removed from the perforations 122.

It is emphasized that the structure of the elastic member can be modified, for example, in the elastic member 18' as shown in FIG. 4A, the elastic member 18' has an axial length smaller than the perforations 122 and the first sleeve 12. The distance between the ring members 124 is such that the inner diameter of the elastic member 18' is slightly smaller than the maximum radial distance of the card members 14 after the perforations 122, whereby the elastic member 18' can also abut The card members 14 are prevented from being pulled out of the perforations 122.

Referring to FIGS. 3 and 4, in the assembly, the elastic member 18 is first sleeved on the first set 12, wherein the elastic member 18 is before the second set 16 is assembled with the first set 12. Preferably, the bottom end abuts against the annular abutment surface 124 of the first sleeve 12, and one of the elastic members 18 is partially disposed in the first sleeve 12 One of the radial directions is relative to the card members 14, and more particularly, the coil spring has a smaller helical pitch, and the top end portion surrounds the card members 14, thereby ensuring and limiting the card members 14. The perforations 122 are not removed outwardly, thus facilitating subsequent component assembly. Preferably, after the coil spring is rotated at any angle around the first sleeve 12, the elastic member 18 is retained with a portion thereof in a radial direction of the first sleeve 12 relative to the card members 14. These cards 14 are restricted.

Next, the second set 16 is inserted into the first set 12, because the radial distance of the annular protrusion 166 of the second set 16 of the cylindrical member 164 is smaller than the outer diameter of the coil spring, so the coil spring is subjected to the tube The piece 164 of the annular recess 168 is compressed against compression, while the second set 16 has a tendency to move away from the first set 12. When the ring protrusion 166 of the tubular member 164 continues to press the coil spring to the top of one of the first sleeves 12 to be exposed outside the cylindrical member 164, the ring member 162 can be coupled to the top of the first sleeve 12 through the ring member 162. To limit the cylindrical member 164 between the ring member 162 and the ring abutment surface of the first set 12 without coming off the first set 12 due to the top of the coil spring.

It is to be noted that, if the elastic member 18' as shown in FIG. 4A is used, since the inner diameter of the elastic member 18' is slightly smaller than the maximum radial distance of the card members 14 after the perforations 122, Therefore, when assembling, the elastic member 18' can be firstly sleeved on the first sleeve 12 (for example, the elastic member 18' first abuts against the annular abutment surface 124 of the first sleeve 12), and the card member is to be replaced. After the holes 122 are placed, the elastic members 18' are moved up to position the card members 14 at the elastic members 18'. Between two adjacent spirals, the elastic member 18' can be surely abutted against the card members 14, and then the second set 16 is sleeved on the first set 12; or, After the card members 14 are placed in the through holes 122, the elastic members 18' are sleeved on the first set 12 and the card members 14 are located between two adjacent spirals of the elastic members 18'. The elastic member 18' can also abut against the card members 14, and then the second set 16 is sleeved on the first set 12.

The assembly method of the grip 10 will be described below. The method of assembling the grip 10 includes the steps of: providing a first sleeve 12 having a tubular shape and having the perforations 122; providing the clips 14 to the perforations 122; and fitting the elastic members 18 to the first kit 12, one of the elastic members 18 is in a radial direction of one of the first sets 12 relative to the card members 14 and restricts the card members 14 from coming out of the perforations 122; a second set 16 of the first set 12, the elastic member 18 being compressed and resiliently coupled to the first set 12 and the second set 16, the second set 16 being controllably movable relative to the first set 12, The card member 14 is abutted by the second set 16 and controllably enters the interior of the first set 12 with a portion thereof.
