[0028] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0029] Please refer to Figure 1 as well as Figure 2 The handgrip extension and fixing device includes a columnar body 1, with elastic rubber plugs 2 at both ends of the body 1. Each elastic rubber plug 2 has an exposed section 21 that protrudes from the body 1, and the diameter of the exposed section 21 is larger than the diameter of the body 1. The body 1 is also provided with two sets of locking components, which are respectively located near both ends of the body 1. Each set of locking components includes at least one elastic latch 3.
[0030] As can be seen from the above description, the beneficial effects of this utility model are as follows: the hand grip extension and fixing device has a simple structure and can effectively connect two splicing pipes 4. The elastic rubber plug 2 on the hand grip extension and fixing device can make the hand grip extension and fixing device and the splicing pipe 4 fit tightly, effectively improving the shaking phenomenon of the spliced hand grip. Even after multiple disassemblies and reassemblies, the spliced hand grip can still have good structural stability.
[0031] Furthermore, the elastic plug 2 also includes an insertion section 22 connected to the exposed section 21. The insertion section 22 is inserted into the body 1 to be interference-fitted with the body 1. The exposed section 21 is provided with a plurality of breaks 211, which extend from the end of the exposed section 21 away from the insertion section 22 to the insertion section 22.
[0032] As can be seen from the above description, the break 211 on the exposed section 21 allows the exposed section 21 to undergo a certain degree of topographic deformation, thereby allowing the exposed section 21 to better abut against the inner wall of the splicing pipe 4; the connection between the main body 1 and the elastic rubber plug 2 is simple and facilitates the assembly and manufacturing of the hand grip extension fixture.
[0033] Furthermore, the number of breaks 211 on the elastic rubber stopper 2 is multiple, and the multiple breaks 211 are evenly distributed around the central axis of the elastic rubber stopper 2.
[0034] As can be seen from the above description, the evenly distributed multiple elastic rubber plugs 2 can ensure that the elastic rubber plugs 2 are subjected to balanced forces, thereby better improving the shaking phenomenon of the splicing pipe 4 connected to the hand grip extension fixer.
[0035] Furthermore, the elastic clip 3 includes an elastic element 31 and a pin 32. The pin 32 is slidably disposed along the radial direction of the body 1. The peripheral wall of the body 1 has a hole for one end of the pin 32 to extend out. The elastic element 31 is disposed inside the body 1 and contacts the body 1 and the pin 32 respectively.
[0036] As can be seen from the above description, the elastic clamp 3 has a simple structure and stable operation, and the hand grip extension fixing device and splicing pipe 4 are easy to disassemble and assemble.
[0037] Furthermore, the elastic element 31 is a sheet, spring, or spring pad.
[0038] As can be seen from the above description, there are many types of elastic elements 31 to choose from, which helps to enrich the diversity of hand grip extension fixation devices.
[0039] Please refer to Figure 3 The splicing grip bar includes at least two splicing tubes 4 and several of the aforementioned grip bar extension and fixing devices. Two adjacent splicing tubes 4 are connected by the grip bar extension and fixing devices. The end of the main body 1 is inserted into the splicing tube 4. The splicing tube 4 is provided with a locking hole 41 that cooperates with the elastic locking head 3. The exposed section 21 abuts against the inner wall of the splicing tube 4.
[0040] As described above, the modular handle is easy to assemble and disassemble, convenient for storage and transportation, has good structural stability, and is not prone to wobbling at the joints, resulting in a good user experience.
[0041] Furthermore, the end of the splicing pipe 4 is provided with an elastic sleeve 5, the elastic sleeve 5 has an abutting ring portion, the inner diameter of the abutting ring portion is smaller than the inner diameter of the splicing pipe 4, and the inner peripheral wall of the abutting ring portion abuts against the outer wall of the main body 1.
[0042] As described above, the elastic rubber sleeve 5 can press against the outer wall of the main body 1, thereby further improving the structural stability of the spliced hand grip and improving the phenomenon of easy shaking at the splicing point of the spliced hand grip.
[0043] Furthermore, the elastic sleeves 5 on two adjacent splicing pipes 4 are in contact with each other, or there is a gap between the elastic sleeves 5 on two adjacent splicing pipes 4.
[0044] As described above, the contact between the elastic rubber sleeves 5 on two adjacent splicing pipes 4 can greatly improve the structural stability of the spliced grip bar and further improve the phenomenon of easy shaking at the splicing point of the spliced grip bar; the gap between the elastic rubber sleeves 5 on two adjacent splicing pipes 4 can reduce the processing accuracy requirements, thereby saving manufacturing costs.
[0045] Please refer to Figure 4 Leveler, including the aforementioned spliced hand grip.
[0046] As can be seen from the above description, this leveling tool has a good handling feel and a good user experience.
[0047] Furthermore, a hand grip ring 7 is detachably installed on the spliced hand grip bar.
[0048] As described above, the handheld ring 7 provides a handhold position for the user, making it convenient for the user to operate the leveler.

[0050] The elastic stopper 2 further includes an insertion section 22 connected to the exposed section 21. The insertion section 22 and the exposed section 21 are integrally formed. The insertion section 22 is inserted into the body 1 to fit the body 1 with an interference fit. The exposed section 21 has a plurality of breaks 211, which extend from the end of the exposed section 21 away from the insertion section 22 to the insertion section 22. Preferably, the elastic stopper 2 has multiple breaks 211, which are evenly distributed around the central axis of the elastic stopper 2. In this embodiment, the elastic stopper 2 has four breaks 211.
[0051] Specifically, the elastic locking head 3 includes an elastic element 31 and a pin 32. The pin 32 is slidably disposed along the radial direction of the body 1.

[0053] In one or more embodiments, the elastic sleeves 5 on two adjacent splicing pipes 4 are in contact with each other. In this embodiment, there is a gap between the elastic sleeves 5 on two adjacent splicing pipes 4.
[0054] Please combine Figure 4 This embodiment also provides a leveling device for leveling loose soil piles, fertilizer piles, etc. The leveling device includes the above-mentioned spliced hand handle and leveling frame 6, with one end of the spliced hand handle connected to the leveling frame 6.
