In order to ensure that the spline shaft 110 can interact with the internal spline hole 205 to ensure the limitation of the installation cylinder 201 no matter whether the pull knob 106 is pulled manually or not, in the embodiment, preferably, the spline shaft 110 is installed at one end of the adjusting rod 105 departing from the pull knob 106, the spline shaft 110 is slidably installed inside the installation cylinder 201, the internal spline hole 205 is formed inside the installation cylinder 201, and the internal spline hole 205 and the spline shaft 110 are meshed with each other.

In order to draw the branches close through the S-shaped contact angle steel 203 and increase the friction between the device and the supporting branches to prevent the device from slipping relative to the branches, in this embodiment, it is preferable that the contact angle steel 203 is S-shaped, and an ejector pin 204 is disposed on one side of the contact angle steel 203 away from the supporting steel bar 202.

In order to guarantee that limiting gear 107 can interact with limiting tooth socket 103 under the condition of not receiving any external force, in order to guarantee that adjusting rod 105 can not take place to rotate, and then further guarantee that whole branch fixed establishment 2 can not take place to rotate, in this embodiment, preferably, handle 102 has inside offered movable chamber 104, adjusting rod 105 runs through movable chamber 104, adjusting rod 105 surface is provided with limiting plate 108, limiting plate 108 is arranged in movable chamber 104 inside, adjusting rod 105 surface cover is equipped with return spring 109, return spring 109 is arranged in movable chamber 104 inside, return spring 109 one end and limiting plate 108 side contact, and the return spring 109 other end and movable chamber 104 inner wall contact.

In order to prevent the in-process of just pruning the branch, the device takes place to electrically conduct and causes the injury to operating personnel, makes thimble 204 just in time be in the central point of positive radian to guarantee at the in-process of pulling the branch, the device is more reliable and more stable, and in this embodiment, preferred, thimble 204 is corresponding with installation section 201 position, and the crooked radian of contact screw angle steel 203 is 120, and handle 102 is made for insulating material.

The working principle and the using process of the utility model are as follows: after the installation of the utility model, firstly, the installation and the safety protection of the utility model are checked, then the utility model can be used, when in use, the handle 102 can be held by hand, firstly, the limit plate 108 can be arranged at the rightmost side of the movable cavity 104 under the action of the return spring 109, at the moment, the adjusting rod 105 is arranged at the rightmost side of the stroke, therefore, the limit gear 107 and the limit tooth groove 103 can be mutually limited, in the adjustment process, the spline shaft 110 is always arranged in the inner spline hole 205, so as to ensure that the spline shaft 110 can only slide along the axis of the installation cylinder 201 and can not relatively rotate, at the moment, the rotation of the handle 102 can drive the inner adjusting rod 105 to rotate through the matching of the limit tooth groove 103 and the limit gear 107, because the installation cylinder 201 is arranged at the end part of the supporting rod 101 through a bearing, therefore, the installation cylinder 201 can rotate relative to the supporting rod 101, the spline shaft 110 is always mutually matched with the inner spline hole 205, therefore, when the adjusting rod 105 rotates to drive the installation cylinder 201 to rotate, the angle of the installation cylinder can be adjusted, the contact thread angle steel 203 is S-shaped, namely the contact thread angle steel 203 has two opposite radians and increases friction with branches, when in use, the contact thread angle steel 203 with the front radian can be matched with a supporting branch and further fixed with the supporting branch through the thimble 204, then the distant branch is pulled close through the reverse radian, at the moment, the thimble 204 is used as a supporting point to rotate the device, so that the branch is pulled close, and the supporting branch is not necessarily in a vertical state under special conditions, therefore, the contact thread angle steel 203 is necessarily inclined, the whole device is longer, the forward radian of the contact thread angle steel 203 cannot be matched with the supporting branch in the rotating process of one-hand operation, at the moment, the pull knob 106 can be pulled out manually, the limit gear 107 can be separated from the limit tooth groove 103, the return spring 109 stores power, at the moment, the installation cylinder 201 can be driven to rotate by rotating the pull knob 106, then the contact thread angle steel 203 is driven to rotate, the pull knob 106 can be loosened after adjustment, the limiting gear 107 and the limiting tooth groove 103 can be enabled to interact again due to the fact that the movable cavity 104 stores power in advance, and the contact thread angle steel 203 can not rotate relatively, so that the forward contact thread angle steel 203 can be matched with a supporting branch to guarantee stability of the device.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
