DETAILED DESCRIPTION

[0030] Reference Figures 2 to 4 The embodiments of the present utility model are further described.

[0031] The specific structure of this embodiment includes: Figure 2 As shown: a blade body 1 and a handle, wherein the blade body 1 has a strip-shaped unit element 2 on the end surface away from the construction thereof, and has a continuous tooth shape on the side of the blade body 1. The unit element 2 and the blade body 1 are integrally formed, and a slide groove 20 is opened on the symmetrical side walls of the unit element 2, and the slide groove 20 is V-shaped.

[0032] The handle comprises a handle body 3 and a shell 4, the shell 4 has a first connection portion 5 and a second connection portion 6, and the end of the handle body 3 is connected to the first connection portion 5 through a connector 7. The connector 7 can control the angle of the handle body 3 to facilitate different processing requirements.

[0033] The connecting member 7 includes a rotating shaft 71 and a joint 72. The rotating shaft 71 and the joint 72 are provided with connecting holes that are interconnected, so that the end of the handle body 3 passes through the connecting hole of the joint 72 and extends into the connecting hole of the rotating shaft 71 to be fixed thereto.

[0034] There is a rod body 31 with an external thread on the end of the handle body 3, and the installation and fixation are achieved by threaded connection between the rod body 31 and the connecting hole of the rotating shaft 71. During this period, the joint 72 is placed on the outside of the first connecting part 5, and a joint pad 73 is provided between the joint 72 and the first connecting part 5. The center of the joint pad 73 has a hole for the end of the handle body 3 to pass through.

[0035] A cavity is provided on the first connecting part 5 for rotationally connecting the rotating shaft 71, and a movable opening 50 connected to the cavity is opened on the first connecting part 5. The diameter of the movable opening 50 is larger than the diameter of the rod body, so that the rod body can move freely in the movable opening 50 along the opening direction of the movable opening 50, thereby satisfying the movement of the handle body 3 relative to the movable opening 50, thereby realizing the adjustment of the construction angle of the handle.

[0036] The second connecting portion 6 is provided with slots (61, 62) for the unit element 2 to extend into, and the inner wall of the slots (61, 62) is provided with a protrusion 63 adapted to the slide groove 20, that is, the protrusion 63 extends into the slide groove 20 of the blade body 1, and the structure of the protrusion 63 matches the groove shape of the slide groove 20 and is triangular. By utilizing the matching relationship between the protrusion 63 and the slide groove 20, the shell 4 can slide back and forth in one direction on the unit element 2 without falling off.

[0037] By installing a locking unit for locking the housing 4 on the single element 2 on the second connecting portion 6 , the handle can be stopped at any position on the single element 2 .

[0038] In order to accommodate the stopping unit, a side opening is also provided on the shell 4. The stopping unit includes a locking tongue 81, a spring 82 and a pin 83. An axial hole penetrating the body of the locking tongue 81 is provided near the end thereof, and a docking hole concentric with the axial hole is provided on the shell 4 at a position corresponding to the axial hole. The pin 83 penetrates the axial hole and is connected to the docking hole. The locking tongue 81 is placed in the side opening, and the end of the locking tongue 81 contacts the unit element 2. One end of the spring 82 is connected to the inner wall of the locking tongue 81, and the other end is connected to the inside of the shell 4.

[0039] When used as described above, by pressing the top edge of the locking tongue 81, the spring 82 contracts backwards, and the end of the locking tongue 81 is lifted upward to break away from the interference with the unit element 2. The handle 3 is held and pulled to cause the shell 4 to slide relative to the unit element 2 to a desired position. The pressure on the locking tongue 81 is released, and after the spring 82 recovers, the end of the locking tongue 81 continues to be in interference and extrusion with the end face of the unit element 2, and the shell 4 can no longer be pulled to slide on the unit element 2.

[0040] like Figure 2 and Figure 3 As shown: since there are two notches (61, 62) on the second connecting portion 6, and the two notches (61, 62) are respectively opened in the front end face and the side end face direction of the shell body 4, and the specifications of the two notches (61, 62) are the same, the purpose of setting the two notches (61, 62) is to enable the shell 4 to realize the installation relationship of the single component 2 in two directions, so that the handle and the blade body 1 can be installed in two dimensional directions, that is, the gripping direction of the handle body 3 of the handle can be four directions: front, back, left and right, thereby meeting different construction working conditions.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
