[0028] Specifically, the hose conveying support assembly includes two rollers 2 rotatably installed between the inner walls on both sides of the U-shaped support 1, and a brake motor 202 is fixedly installed on the right side of the U-shaped support 1 with an output shaft fixedly connected to the right end of the front roller 2. Two annular placement grooves 201 are provided on the outer side of the roller 2, and the inner walls of the annular placement grooves 201 are adhered and covered with anti-slip rubber; the brake motor 202, roller 2, annular placement grooves 201 and anti-slip rubber are arranged to cooperate to place the two hoses in the corresponding two front and rear opposite annular placement grooves 201 respectively, and the two front and rear opposite annular placement grooves 201 are used to support the corresponding hoses, and when the brake motor 202 is started, the front roller 2 is driven to rotate, and the front roller 2 drives the corresponding anti-slip rubber to rotate and frictionally drive the hose to move forward or backward, thereby realizing the conveying and supporting of the hose.

[0029] Furthermore, the elastic vertical guide assembly includes a T-shaped guide rod 502 fixedly connected to the top of the connecting plate 501, and the fixed plate 5 is slidably mounted on the two T-shaped guide rods 502, wherein the top of the fixed plate 5 is provided with two vertical guide holes that are respectively slidably mounted on the outer sides of the corresponding T-shaped guide rods 502, which play the role of allowing the T-shaped guide rods 502 to pass through and guide their vertical sliding. Two springs 503 are fixedly connected between the bottom of the fixed plate 5 and the top of the connecting plate 501, and the springs 503 are movably mounted on the corresponding T-shaped guide rods 502. Two avoidance holes are provided at the bottom of 302, and the avoidance holes are located above the corresponding T-shaped guide rod 502 and adapted to the T-shaped guide rod 502; the T-shaped guide rod 502 and the spring 503 are cooperated, and when the two punching nails 4 move downward and drive the fixed plate 5 to move downward, the fixed plate 5 drives the connecting plate 501 to move downward through the two springs 503, and when the connecting plate 501 moves downward to a point where it can no longer move downward, the fixed plate 5 that continues to move downward compresses the two springs 503 downward, and utilizes the spring 503 in a compressed state to realize elastic tightening of the connecting plate 501 downward.

[0030] Furthermore, the pressing assembly includes a vertical tube 504, and the adjacent sides of the two vertical tubes 504 are fixedly connected to the two sides of the connecting plate 501 respectively. The vertical tubes 504 are movably sleeved on the corresponding punching nails 4, and the outer bottom of the vertical tube 504 is fixedly sleeved with an arc-shaped pressing plate 505, wherein the top of the arc-shaped pressing plate 505 is provided with a sleeve hole fixedly connected to the outer side of the corresponding vertical tube 504, and the bottom of the arc-shaped pressing plate 505 is bonded and fixed with an anti-slip rubber pad, and the bottom of the anti-slip rubber pad is provided with a circular through-hole connected to the inside of the corresponding vertical tube 504, and the arc-shaped pressing plate 505 is located above the corresponding annular placement groove 201; The vertical tubes 504, arc-shaped pressure plates 505 and anti-slip rubber pads are arranged in cooperation. When the connecting plate 501 moves downward, the two vertical tubes 504 will drive the two arc-shaped pressure plates 505 to press down on the top of the two hoses. The arc-shaped pressure plates 505 are blocked and restricted by the hoses and no longer move downward, so that the connecting plate 501 no longer moves downward. The elastically tightened connecting plate 501 is used to elastically tighten the two arc-shaped pressure plates 505 through the two vertical tubes 504 to achieve synchronous compression of the two hoses. The U-shaped lifting plate 302 that continues to move downward while gradually tightening is used to drive the two punching nails 4 to pass downward from the two vertical tubes 504 to perform the punching work.

[0031] Furthermore, the limit touch control assembly includes a scale 506 fixedly connected to the top of the connecting plate 501, the fixed plate 5 and the U-shaped lifting plate 302 are both slidably sleeved on the scale 506, and a sliding sleeve 507 is slidably sleeved on the scale 506. The left side of the scale 506 is movably contacted with a knob-type bolt 508, and the sliding sleeve 507 is threadedly sleeved on the knob-type bolt 508. A threaded hole is provided on the left side of the sliding sleeve 507 to be threadedly connected to the knob-type bolt 508, and the right side of the sliding sleeve 507 is provided with a threaded hole to be threadedly connected to the knob-type bolt 508. The top of the side is fixedly connected with a reverse start switch 509 electrically connected to the electric push rod 301. The reverse start switch 509 is located below the fixed plate 5 and cooperates with the fixed plate 5; the provided scale 506, sliding sleeve 507, knob-type bolt 508 and reverse start switch 509 cooperate. When the connecting plate 501 is restricted and cannot move further downward, the fixed plate 5 that continues to move downward will continue to move downward with the punching nail 4. At this time, the fixed plate 5 slides downward on the scale 506 until it moves downward to the reverse direction. The start switch 509 is squeezed and touched, and the reverse start switch 509 controls the electric push rod 301 to start in the reverse direction to recover and reset, so as to limit the depth of the downward drilling. In addition, when it is necessary to adjust the limit position of the fixed plate 5 according to the depth of different drilling, the knob-type bolt 508 is rotated in the reverse direction to separate it from the scale 506 to release the lock of the sliding sleeve 507. The personnel moves the sliding sleeve 507 upward to slide it upward on the scale 506, and the sliding sleeve 507 drives the reverse start switch 509 to move upward. The personnel judges the adjustment distance by observing the position where the top of the sliding sleeve 507 is aligned with the scale 506. After the adjustment is appropriate, the knob-type bolt 508 is rotated forward to squeeze it with the scale 506 to lock the adjusted sliding sleeve 507. By adjusting the reverse start switch 509 up and down, the limit position of the fixed plate 5 can be flexibly adjusted according to the use requirements, so as to flexibly adjust the depth of the punching nail 4 that can be penetrated for drilling, which is convenient for drilling hoses with different thicknesses.

[0032] The method of use of this embodiment is as follows: two rubber hoses to be punched are placed on the top of the inner side of the two corresponding annular placement grooves 201 opposite to each other, and the brake motor 202 is started to drive the front roller 2 to rotate. The front roller 2 drives the corresponding anti-slip rubber to rotate and rub to drive the rubber hose forward or backward. When the position where the hole needs to be punched is transported to the bottom of the corresponding punching nail 4, the person turns off the brake motor 202 and starts the electric push rod 301 in the forward direction. The electric push rod 301 drives the U-shaped lifting plate 302 to move downward. The U-shaped lifting plate 302 drives the two punching nails 4 to move downward. The two punching nails 4 drive the fixed plate 5 to move downward. The fixed plate 5 is connected to the two springs 503. The connecting plate 501 is driven to move downward, and the connecting plate 501 drives the two arc pressure plates 505 to press down on the top of the two hoses through the two vertical tubes 504. The arc pressure plates 505 are blocked and restricted by the hoses and no longer move downward, so that the connecting plate 501 no longer moves downward. At this time, the fixing plate 5 that continues to move downward slides downward on the two T-shaped guide rods 502 and compresses the springs 503. The springs 503 in the compressed state are used to elastically tighten the connecting plate 501 downward, thereby elastically tightening the two arc pressure plates 505, so as to achieve synchronous tightening and fixing of the two hoses. At this time, the two punching nails 4 that continue to move downward are respectively moved downward from the corresponding vertical tubes 504 and perform punching work on the hoses.

[0033] When the connecting plate 501 stops moving downward and the fixed plate 5 continues to move downward to perform elastic tightening, the fixed plate 5 still slides downward on the scale 506 until it moves downward to press the reverse start switch 509, and the reverse start switch 509 controls the electric push rod 301 to start in the reverse direction to perform the recovery and reset work, thereby driving the U-shaped lifting plate 302, the punching nail 4 and the fixed plate 5 to rise and reset, and releasing the compression force on the spring 503. After the compression force is released, the fixed plate 5 that continues to move upward and reset is sequentially brought into contact with the two springs 503, the connecting plate 501 and the two vertical pipes 504. The two arc-shaped pressure plates 505 are raised and reset, and then the brake motor 202 can be started again to transport the hose, and the next position where a hole needs to be punched is reached. The electric push rod 301 is started forward again to punch. By automatically transporting the hose separately, it is not limited by the punching spacing, which allows personnel to flexibly control the punching position according to usage requirements, thereby improving usage flexibility. In addition, the two hoses can be automatically and synchronously elastically tightened and pressed during the downward punching work, reducing the risk of hose displacement and shaking during punching, and no separate fixation is required, which is convenient to use.

[0034] When the screwdriver 508 is in the locked position, the screwdriver 508 is in the locked position, and the screwdriver 508 is in the locked position, so that the screwdriver 508 is locked.
