DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Combination Figures 1 to 4 The present embodiment describes an adjustable multi-head hole puncher, which includes a cross bar 1, wherein the cross bar 1 is provided with a plurality of mounting holes 2 along the length direction, a hole puncher 3 is fixed on the cross bar 1 through the mounting holes 2, and an adjustable limit rod 4 is provided on the hole puncher 3, when the cross bar 1 is pressed down, the limit rod 4 on the hole puncher 3 abuts against the cross bar 1 to control the punching depth, and at the same time, a handle 6 is fixedly connected to the upper end surface of the cross bar 1 through two connecting rods 5.

[0023] The structure of the crossbar 1 is a U-groove structure composed of two bent steel plates, which improves the strength of the crossbar 1 and avoids excessive punching of holes on the crossbar 1, which would result in insufficient strength of the crossbar 1.

[0024] The mounting holes 2 are arranged at equal intervals, and the mounting holes 2 include round holes 201 and straight slots 202, and the round holes 201 and the straight slots 202 are arranged alternately, and the length of the straight slots 202 is not less than twice the diameter of the round holes 201, and the width of the straight slots 202 is the same as the diameter of the round holes 201. The straight slots 202 serve as a common mounting port for the round holes 201 on both sides, and can also be slightly adjusted during installation.

[0025] like Figure 2 As shown, bending structures 101 are provided at both ends of one side of the cross bar 1, and a ruler 7 is movably inserted between the two bending structures 101. When distance measurement is required, the ruler 7 is pulled out from the bending structure 101, and the position of the puncher 3 is quickly located using the ruler 7. Each scale on the ruler 7 corresponds to the center point position of the mounting hole 2, thereby ensuring the accuracy of positioning.

[0026] like Figure 3-4As shown, the punch 3 includes a punching tube 301, and brackets 302 are fixedly connected to both sides of the upper end of the punching tube 301. The brackets 302 pass through the mounting holes 2 and are connected to the cross bar 1. A positioning plate 303 is arranged on the outer side of the lower end of the punching tube 301, and the positioning plate 303 is elastically connected to the bracket 302. Specifically, threaded rods 304 are arranged on the two brackets 302, and the two threaded rods 304 are inserted into two adjacent mounting holes 2, and the threaded rods 304 are located on the upper side of the cross bar 1. The threaded rods 304 are threadedly connected with fastening nuts 305, and the fastening nuts 305 limit the upper part of the threaded rods 304 to prevent the threaded rods 304 from coming out of the mounting holes 2, so as to install the punch 3 on the cross bar 1, and gaskets 306 are sleeved on both upper and lower sides of the threaded rods 304 located on the cross bar 1. The bracket 302 is provided with a limit block 307, and the positioning plate 303 is fixedly connected with a light rod 308, and the light rod 308 slides through the limit block 307, and a spring 309 is fixedly connected between the limit block 307 and the positioning plate 303, and the upper end of the light rod 308 is fixedly connected with a cap 310. When the cross bar 1 is pressed down, the cross bar 1 acts on the punching cylinder 301 through the bracket 302, so that the punching cylinder 301 moves downward, so that it is inserted into the soil to punch holes. After the punching is completed, the handle 6 is pulled upward, and the punching cylinder 301 is quickly pulled out of the soil under the action of the spring 309, and the punching cylinder 301 is restored to its original position.

[0027] A nut sleeve 311 is fixedly connected to the side of the punching tube 301, and the limit rod 4 is threadedly connected to the nut sleeve 311. When the cross bar 1 is pressed down, due to the elastic force of the spring 309, the punching tube 301 will initially move upward relative to the cross bar 1. When it moves to the point where the limit rod 4 abuts against the cross bar 1, the cross bar 1 acts on the limit rod 4 to drive the punching tube 301 to be inserted into the soil.

[0028] Meanwhile, a filling port 312 is provided at the upper end of the punching tube 301 , and the filling port 312 is an inclined groove, so as to facilitate the discharge of soil from the punching tube 301 during the insertion process.

[0029] The working principle of the utility model is as follows: a plurality of mounting holes 2 are arranged on the cross bar 1, and a puncher 3 is fixed on the cross bar 1 through the mounting holes 2, so that a plurality of planting holes can be punched at one time, and the punching hole spacing can be conveniently adjusted, thus saving the distance measurement time, the hole spacing is the same, the arrangement is neat, and the punching efficiency is improved.
