As shown in Figures 1 to 6, negative drawing unlock retractable spontoon includes holding rod 1, strike bar 2, unlock driving mechanism 3, solution Latch mechanism 4 and connector 5.

One end of strike bar 2 is plugged in holding rod 1；Card slot 11 is equipped in the front inner wall of holding rod 1；After holding rod 1 End is connected with unlock driving mechanism 3, unlocking mechanism 5 is connected in the rear end of strike bar 2, in unlock driving mechanism 3 and solution lock machine Connector 5 is equipped between structure 4.

As shown in Fig. 2, Fig. 4 to Figure 10, the unlock driving mechanism 3 includes pedestal 31, compression bar 32, briquetting 33, connecting rod Mechanism 34 and swing arm 35.

The pedestal 31 includes base body 311 and two supporting arms extended forward from the front end of base body 311 312.The outer diameter of base body front end 3111 is less than the outer diameter of pedestal ontology rear end 3112, on 3111 outer wall of base body front end Equipped with external screw thread, there is cavity 3113 from back to front in base body, top plate 3114, top plate envelope are equipped in the front end of base body The front end for blocking cavity is equipped with through-hole 3115 on top plate 3114.Base body front end 3111 is connected to holding rod 1 by external screw thread On the inner wall of rear end, since base body front end external diameter is less than base body rear end outer diameter, when pedestal 31 is connected on holding rod 1 Afterwards, 1 outer diameter of outer diameter with holding rod of base body rear end 3112 is essentially identical.There is gap 3121 between two supporting arms 312.

The front end of compression bar 32 passes through through-hole 3115, and the rear end of compression bar 32 is located in cavity 3113.Briquetting 33 is connected to compression bar 32 rear end, in the present embodiment, briquetting 33 are circle, and briquetting 33 is located in cavity 3113, between briquetting 33 and cavity inner wall There is gap.

The link mechanism 34 includes link block 341 and connecting rod 342, and link block 341 is connected to the front end of compression bar 33, even One end of bar 342 is hinged on one end of link block 341.One end of swing arm 35 is hinged on the other end of connecting rod.In swing arm 35 Portion is hinged on two supporting arms 312, has a connecting pole 351 in the other end of swing arm 35, the middle part and swing arm of connecting pole 351 it Between have gap 352.Dynamic clamping head and quiet clamping head 36 is cased between top plate 3114 and briquetting on compression bar 32, dynamic clamping head and quiet clamping head 36 is bullet Spring.

As shown in Fig. 2,4,5,6 and Figure 11 to Figure 14, the unlocking mechanism 4 includes deck 41, snap ring 42, unlock Bar 43 and elastic component 44.

The outer diameter of deck front end 411 is less than the outer diameter of deck rear end 412, and 411 outer wall of deck front end is equipped with external screw thread, card Seat is threadedly attached on the inner wall of strike bar, since the outer diameter of deck front end 411 is less than the outer diameter of deck rear end 412, because This can allow the outer diameter of the outer diameter and strike bar 2 of deck rear end essentially identical after deck is installed on strike bar 2.Deck 41 There is foreboard 413, foreboard 413 to be equipped with first through hole 4131 for front end, blocking part 414 is equipped in deck 41, in blocking part 414 It is equipped with the second through-hole 4141, accommodating cavity 415 is equipped with positioned at the front of blocking part 414 in deck 41, is equipped on deck 41 The sliding vallecular cavity 416 communicated with accommodating cavity 415 radially extended, in the present embodiment, sliding vallecular cavity are provided with two, two cunnings Dynamic vallecular cavity 416 is oppositely arranged relative to the center of deck.

The snap rings 421 that the snap ring 42 is oppositely arranged including two relative to deck center are with setting in two snap rings Between resetting spring 422.Snap ring 421 includes snap ring ontology 4211, is located at 4212 and of fastening part in 4211 outside of snap ring ontology The solution lock ear 4213 being arranged on the inside of snap ring ontology, the thickness of fastening part 4212 are less than the thickness of snap ring ontology 4211, two snap rings On solution lock ear shifted to install in front-rear direction, the solution lock ear on two snap rings have overlapping bit, solution lock ear 4213 on be equipped with solution Lockhole 42131, solution lockhole are waist-shaped hole, and the solution lockhole in two solution lock ears has the overlapping bit being mutually communicated.In no sliding groove Intracavitary sliding is equipped with snap ring 421.

Unlock rod 43 passes through the second through-hole, solution lockhole, first through hole.Unlock rod 43 includes big end 431, small end 432 With interconnecting piece 433, interconnecting piece 433 is truncated cone-shaped, and big end 431 is connected to the front end of interconnecting piece 433, and small end 432 is connected to The rear end of interconnecting piece 433 is connected in small end 433 and keeps out draw ring portion 46, keeps out the rear end that draw ring portion 46 is located at blocking part, Blocking part 414, which is withstood, keeps out draw ring portion 46, and connecting hole 461 is equipped on keeping out draw ring portion 46.It is set in the front end of big end 431 It is spring to have baffle 45, elastic component 44, and spring pocket is on the unlock rod positioned at baffle 45 and foreboard.

It is equipped with connection ring 50 on connecting hole 461, connector 5 is connected between connecting pole 351 and connection ring 50, connects Part is flexible strand etc..

Above-mentioned negative drawing unlocks retractable spontoon, when not pressing briquetting 33, since elastic component 44 is to baffle 45 It acts on, keeps out draw ring portion 46 under the action of elastic component 44 and kept out by blocking part 414.Such as need use baton, throw away forward or Strike bar 2 is pulled out, when snap ring 42 moves at card slot 11, snap ring 421 is under the action of resetting spring 422 to outward transport It is dynamic, it allows in fastening part 4212 holding to card slot 11, avoids strike bar retraction, in the present invention, be located between two snap rings The both sides of unlock rod are respectively equipped with resetting spring 422.Strike bar 2 of retracting such as is needed, briquetting 33 is pressed, briquetting 33 drives compression bar 32 The elastic force of dynamic clamping head and quiet clamping head 36 is overcome to travel forward, compression bar 32 drives link block 341 to move, and link block 341 drives connecting rod 342 to transport Dynamic, connecting rod 342 drives swing arm 35 to swing, and swing arm 35 pulls connector 5, the drive of connector 5 to keep out draw ring portion 46 and move backward, support Gear draw ring portion 46 drives unlock rod 43 that the elastic force of elastic component 44 is overcome to move backward, under the guiding role of interconnecting piece 433, allows big End 431 is inserted into solution lockhole, is promoted the elastic force that the fastening part of snap ring overcomes resetting spring to be detached from card slot 11, will be hit bar 2 It retracts.In this configuration, by reversely installing unlock rod, the small end of unlock rod is allowed to be arranged backwards, and solution is realized using pulling force Lock, unlock rod only need to be arranged in the rear end of strike bar and occupy the little space of strike rod rear end returning for strike bar can be realized It receives, after hitting bar recycling, unlocking mechanism is located in the rear end of outer tube, and having been released in the middle front end of outer tube largely can profit With space, which can install other such as capsicum water bottles, torch auxiliary.Therefore, the unlock rod setting gram of the utility model The technology prejudice that existing unlock rod is arranged forward is taken.Using link mechanism, organization volume is small, and can realize the reversed company of pulling The purpose of fitting.
