DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the pruning device with the telescopic mechanism will be clearly and completely described below with reference to the drawings in the embodiments of the pruning device with the telescopic mechanism. Obviously, the described embodiments are only part of the embodiments of the pruning device with the telescopic mechanism, but not all the embodiments. Based on the embodiments of the pruning device with the telescopic mechanism, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the pruning device with the telescopic mechanism.

[0016] Please refer to Figures 1-4The utility model provides a technical scheme: a tree pruning device with telescopic mechanism, including pruning shears main part 1 and extension thread sleeve 2, pruning shears main part 1 includes the first handle 11 of holding with blade 13 and the second handle 12 of holding, the first handle 11 of holding and the second handle 12 of holding are hinged through first pin shaft 14, the outer wall of first handle 11 and second handle 12 all are set with recess 15, the inside of recess 15 is hinged with telescopic handle 17 through second pin shaft 16, and the other end of telescopic handle 17 is connected with threaded column 18, and extension thread sleeve 2 is screwed on the outer wall of threaded column 18.

[0017] The end of telescopic handle 17 close to threaded column 18 is slidably inserted with lock column 19, and the inner wall of recess 15 is set with the lock groove 110 corresponding to the position of lock column 19, so that the telescopic handle 17 can be locked when the lock column 19 is inserted into the lock groove 110, and the accidental overturning of the telescopic handle 17 can be effectively avoided.

[0018] The end of lock column 19 close to threaded column 18 is fixedly connected with the knob 112, the outer wall between the knob 112 and the telescopic handle 17 of lock column 19 is sleeved with the spring 111, and the setting of the spring 111 can reset the lock column 19.

[0019] The outer wall of the first handle 11 and the second handle 12 of holding are all set with arc chamfer, and the outer wall of the telescopic handle 17 is set with arc edge matched with the arc chamfer, so that the handle together with the telescopic handle 17 is more comfortable when holding.

[0020] Specifically, when using the utility model, in the shortest state, as shown in the accompanying drawings Figure 3 and Figure 4 , at this time, the extension thread sleeve 2 is not set, and the telescopic handle 17 is retracted into the recess 15, when using in this state, the first handle 11 and the second handle 12 of holding can be used to prune the branches of trees;

[0021] In the first extension, the telescopic handle 17 is turned over 180° from the inside of the recess 15 to the outside, so that the telescopic handle 17 and the handle are located on a straight line, at this time, a threaded hoop is sleeved on the threaded column 18, the threaded hoop is locked and continuously moves upward, the threaded hoop will push the knob 112 to drive the lock column 19 to be inserted into the inside of the lock groove 110, so that the telescopic handle 17 is locked, and the accidental overturning of the telescopic handle 17 in the process of using the pruning shears can be effectively avoided;

[0022] In the second extension, the threaded hoop is replaced by the extension thread sleeve 2 threaded to the threaded column 18 in the state of the first extension, and the lock column 19 can be locked in the same way;

[0023] In the once-extended and twice-extended states, the length of the holding handle can be extended to multiple times of the original length, so that the length of the holding handle of the pruning shears can be effectively greatly increased, and the device can effectively prune the branches of trees at high positions.

[0024] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
