One end of the telescopic rod 2 is connected to the connection base 1, and the other end can be fixed on the ground. When the handheld screw pile driver is working, the telescopic rod 2 is arranged tilted, and the axis of the telescopic rod 2 and the axis of the auger rod of the handheld screw pile driver are in the same vertical plane.

[0031] When the handheld spiral pile driver is working, the axis of the spiral drill rod drills vertically into the ground, one end of the telescopic rod 2 is connected to the connecting seat 1, and the other end is fixed on the ground and the telescopic rod 2 is in an inclined state; the connecting rod 4, the ground and the handheld spiral pile driver form a triangle, so that the handheld spiral pile driver is supported on the ground when working. As the spiral drill rod drills into the ground, the telescopic rod 2 can also maintain the vertical state of the spiral drill rod by telescoping. Most of the force of the entire handheld spiral pile driver when working is applied to the telescopic rod 2. The operator only needs to guide the spiral drill rod to a vertical state through the contact between the hand and the connecting seat 1, and the entire working process does not require the operator to pay heavy labor; even with the development of the large-scale process of the handheld spiral pile driver, the weight of the handheld spiral pile driver gradually increases, and most of the load when it is used is also borne by the telescopic rod 2, and the operator can still operate it by hand-guided guidance.

[0032] Specifically, the telescopic rod 2 includes a pipe 21 and a rod 22. One end of the pipe 21 is detachably connected to the connection seat 1. One end of the rod 22 is inserted into the pipe 21 from the end of the pipe 21 away from the connection seat 1. The other end of the rod 22 can be fixed on the ground. The rod 22 and the pipe 21 are frictionally connected, and the handheld spiral pile driver is supported by the friction between the rod 22 and the pipe 21.

[0033] Specifically, this embodiment also includes a fixing nail 3 and a fixing plate 31. The fixing nail 3 can be inserted downward into the ground. The fixing plate 31 is fixedly connected to the top of the fixing nail 3. The fixing plate 31 is used to press the end of the rod 22 connected to the ground against the ground when the fixing nail 3 is inserted into the ground.

[0034] Specifically, one end of the rod 22 connected to the ground is fixedly connected with two fixing plates 221 coaxial with the rod 22, the fixing nail 3 passes through between the two fixing plates 221, and the fixing plate 31 presses the part of the rod 22 between the two fixing plates 221 to press the rod 22 to the ground.

[0035] Specifically, a connecting rod 4 is hinged on the connecting seat 1, and the pipe fitting 21 and the connecting rod 4 are detachably connected together. When the pipe fitting 21 and the connecting rod 4 are connected together, the pipe fitting 21 and the connecting rod 4 are coaxial, and the rotation axis of the connecting rod 4 on the connecting seat 1 is horizontal and perpendicular to the axis of the connecting rod 4.

[0036] A clearance groove 41 is provided on the outside of the connecting rod 4, and a movable part 5 is provided in the clearance groove 41. The movable part 5 can be embedded in and extended out of the clearance groove 41. A clamping groove 53 is provided on the side of the movable part 5 extending out of the clearance groove 41. An elastic part 6 for pushing the movable part 5 to extend out of the clearance groove 41 is provided in the clearance groove 41. A clamping ring is fixedly connected to the inner side of one end of the pipe fitting 21 connected to the connecting rod 4, and the clamping ring can be clamped into the clamping groove 53 of the movable part 5. When the pipe fitting 21 is connected to the connecting rod 4, the pipe fitting 21 is sleeved outside the connecting rod 4 and the clamping ring in the pipe fitting 21 is clamped into the clamping groove 53 of the movable part 5. The blocking of the movable part 5 prevents the pipe fitting 21 from detaching from the connecting rod 4 along the axial direction, thereby realizing the connection between the pipe fitting 21 and the connecting rod 4.

[0037] Specifically, the movable member 5 includes a rotating rod 51 and a clamping block 52. The end of the rotating rod 51 away from the connecting seat 1 is rotatably connected to the connecting rod 4. The length direction of the rotating rod 51 is in the same plane as the axis of the connecting rod 4, and the plane is perpendicular to the rotation axis of the rotating rod 51. The clamping block 52 is fixedly connected to the side of the rotating rod 51 away from the axis of the connecting rod 4, and the clamping groove 53 is formed between the two clamping blocks 52. When the elastic member 6 is in a normal state, the clamping block 52 and the clamping groove 53 are located outside the clearance groove 41.

[0038] When connecting the pipe fitting 21 to the connecting rod 4, first rotate the connecting rod 4 into the giving way groove 41 so that the clamping groove 53 and the clamping block 52 are located in the giving way groove 41, so that the pipe fitting 21 and the clamping ring can be sleeved on the outside of the connecting rod 4. When the clamping ring is aligned with the clamping groove 53, under the elastic action of the elastic member 6, the connecting rod 4 is rotated out of the giving way groove 41, so that the clamping block 52 and the clamping groove 53 are rotated out of the giving way groove 41, so that the clamping ring is embedded in the clamping groove 53, thereby realizing the connection between the pipe fitting 21 and the connecting rod 4.

[0039] The side of the clamping block 52 away from the connection seat 1 is set as an inclined surface, and the side of the inclined surface away from the axis of the connecting rod 4 is inclined toward the direction close to the connection seat 1. Through the setting of the inclined surface, when the pipe 21 and the clamping ring are sleeved on the connecting rod 4, the rotating rod 51 can be pushed to rotate into the clearance groove 41 through the action of the clamping ring and the inclined surface.

[0040] Specifically, the elastic member 6 is configured as a spring, which is located at the side of the rotating rod 51 near the connecting seat 1 at the hinge between the rotating rod 51 and the connecting rod 4, and the spring is located at the side of the rotating rod 51 near the connecting rod 4. The two ends of the spring are respectively fixedly connected to the rotating rod 51 and the groove wall of the yield groove 41.

[0041] Specifically, when the auger rod of the handheld auger pile driver is in a working state with its axis vertical, the top of the connection seat 1 is horizontal, and a level gauge is provided on the top of the connection seat 1 to detect whether the top of the connection seat 1 is horizontal. The level gauge can facilitate the operator to determine whether the auger rod is in a vertical state when the handheld auger pile driver is working.

[0042] Specifically, a plurality of handles 11 are provided on the side of the connection base 1. The arrangement of the handles 11 facilitates the operator to hold the connection base 1 to guide the auger rod of the handheld auger pile driver to be in a vertical state.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
