In order to solve the technical problems, the invention is realized by the following technical scheme:

the invention relates to an elongated terminal sleeve for a pneumatic wrench, which comprises a cylinder body and an elastic piece; one end face of the cylinder is provided with a sleeve opening used for being matched with the terminal cap; the other end of the cylinder body is assembled on a gun nozzle of the pneumatic wrench; an elastic piece is fixedly connected in the sleeve opening; the outer side of the elastic part is matched with a sliding block matched with the inner wall of the looping; the inner wall of the looping is in sliding fit with the peripheral side face of the sliding block.

When people need to unscrew the terminal cap by using a pneumatic wrench, the terminal sleeve is assembled on the pneumatic wrench firstly, then a sleeve opening on the terminal sleeve is matched with the terminal cap, and meanwhile, the terminal cap can extrude an elastic piece and a sliding block in the sleeve opening; when the unscrewing work of the terminal cap is finished and the pneumatic wrench is lifted, the terminal cap in the terminal sleeve is automatically ejected under the pushing action of the elastic piece and the sliding block; therefore, the terminal cap can be quickly unscrewed, the terminal cap in the terminal sleeve can be quickly taken out, and then the terminal cap can be quickly matched and unscrewed with the next terminal cap; the method has the advantages of greatly improving the working efficiency and being convenient to operate.

Furthermore, a placing groove for fixing the elastic piece is formed in the sleeve opening; the placing groove is fixedly connected with the inner side of the elastic piece; the elastic piece is a spring; wherein, the depth of the sleeve opening on the general terminal sleeve is shallow so as to meet the depth of operating the conventional terminal cap; if the placing groove is not arranged, the movable length of the elastic piece is limited, and the matching depth of the sleeve opening on the terminal sleeve and the terminal cap is influenced, so that the working smoothness is influenced; therefore, the placing groove has the function of increasing the moving space of the elastic part and the sliding block so as to ensure a relatively large moving stroke; meanwhile, the matching depth of the sleeve opening on the terminal sleeve and the terminal cap is ensured.

Furthermore, the outer side of the elastic piece is fixedly connected with the sliding block; the inner wall of the sleeve opening is provided with a limiting sliding chute; the limiting sliding groove is in sliding fit with the peripheral side face of the sliding block; the limiting sliding groove has the function that the sliding block cannot slide out of the sleeve opening, so that people can conveniently perform matching operation on the next terminal cap; if one part of the elastic part and the sliding block move out of the sleeve opening, people need to push the sliding block and the terminal cap against each other during operation, and meanwhile, the sleeve opening needs to be matched with the terminal cap; the operation is obviously inconvenient; therefore, the limit sliding groove is needed to limit the moving range of the sliding block to a certain extent.

Furthermore, the inner wall of the limiting chute is uniformly arrayed with limiting clamping grooves; clamping columns are uniformly arrayed on the peripheral side face of the sliding block; the inner wall of the limiting clamping groove is in sliding fit with the clamping column; when the bottom surface of the sliding block is in extrusion fit with the terminal cap and is simultaneously unscrewed, if a certain friction force exists between the bottom surface of the sliding block and the terminal cap, the sliding block is driven to rotate to a certain degree, the elastic piece and the sliding block are in a fixed relation, so that the outer side end of the elastic piece rotates to a certain degree, and the elastic piece deforms and influences the elastic coefficient, the service life and the like when the certain rotation degree exceeds a certain limit; therefore, the limiting clamping groove and the clamping column are used for limiting the sliding block from rotating; thereby having the advantages of prolonging the service life and the like.

Furthermore, the sliding block and the limiting sliding groove are both in regular polygon structures; the purpose is that the function of limiting the sliding block to be incapable of rotating is the same, so that the effect of limiting the sliding block to be incapable of rotating is achieved; thereby having the advantages of prolonging the service life and the like.

Furthermore, the slide block and the limiting sliding groove are uniformly distributed in any one of a regular triangle, a regular quadrangle, a regular pentagon and a regular hexagon; the arbitrary structure can achieve the effect of limiting the sliding block from rotating; thereby having the advantages of prolonging the service life and the like.

Furthermore, a round pipe is fixed on the inner side surface of the sliding block; an elastic part is in clearance fit with the inner wall of the round pipe; the outer wall of the circular pipe is in sliding fit with the inner wall of the placing groove; namely, the slide block and the elastic piece can rotate; therefore, when a certain friction force exists between the terminal cap and the sliding block, the terminal cap drives the sliding block to rotate to a certain degree, and the sliding block drives the outer side part of the elastic part to rotate to a relatively smaller degree; then the influence of the rotation of the slider on the elastic member when the slider rotates will be reduced.

Further, an outer ring of a bearing is fixed on the inner wall of the circular tube; the outer side end of the elastic piece is fixedly connected with an inner ring of the bearing; the purpose of the bearing is to reduce the friction influence between the sliding block and the elastic piece when the sliding block rotates, so that the influence degree on the elastic piece when the sliding block rotates is greatly reduced.

Furthermore, one end of the cylinder body is provided with a lengthening part; the purpose of the lengthening part is to increase the length of the lengthening part, so that the moving space of the elastic part and the sliding block is integrally increased, and a relatively large moving stroke is ensured; meanwhile, the matching depth of the sleeve opening on the terminal sleeve and the terminal cap is ensured.

Furthermore, a through hole is formed in the peripheral side surface of the cylinder; the through hole is used for conveniently observing the states of the elastic element and the sliding block in the sleeve opening.

The invention has the following beneficial effects:

through the action of the cylinder body and the elastic piece, the terminal sleeve assembled on the pneumatic wrench has the function effect of automatically ejecting the terminal cap, so that the terminal cap can be automatically ejected after being twisted off without manual taking-out operation, the operation is convenient, and the working efficiency is greatly improved; the economic effect of enterprises is also obviously improved.
