DETAILED DESCRIPTION

[0030] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0031] Example 1

The tripod 1 is fixedly connected to the front and rear sides of the right side of the base 3. The feed box 2 is provided on the right side of the top of the base 3 by bolt connection. The first slide rail 4 is symmetrically welded on the front and rear right side of the upper base 3. The first slide rail 4 is located on the left side of the feed box 2. A T-shaped slide bar 5 is slidingly arranged between the two first slide rails 4. The cutting knife 6 is fixed to the bottom of the T-shaped slide bar 5. The cutting knife 6 slides between the two first slide rails 4. The handle 7 is fixed to the front and rear sides of the upper part of the T-shaped slide bar 5. The first fixing plate 8 is fixed to the upper inner side of the two first slide rails 4. A first elastic member 9 is connected between the bottom of the first fixing plate 8 and the top of the T-shaped slide bar 5. An adjusting mechanism 10 is provided on the left side of the base 3, and a pushing mechanism 11 is provided on the right side of the feed box 2.

[0033] See Figure 1 and Figure 3As shown, the adjustment mechanism 10 includes a baffle 1001, a sliding sleeve 1002 and a fixing nail 1004. The sliding sleeves 1002 are slidingly provided on both the front and rear sides of the upper part of the base 3. The sliding sleeves 1002 are located on the outside of the two first slide rails 4. The baffle 1001 is fixed between the inner sides of the left parts of the two sliding sleeves 1002. Second positioning holes 1005 are evenly spaced on the front and rear sides of the top right side of the base 3. First positioning holes 1003 are evenly spaced on the top of the sliding sleeve 1002. Fixing nails 1004 are detachably provided between the adjacent first positioning holes 1003 and the second positioning holes 1005.

[0034] See Figure 1 、 Figure 4 and Figure 5 As shown, the pushing mechanism 11 includes a first fixed frame 1101, a first roller 1103, a second fixed frame 1104, a motor 1105, a second roller 1106 and a pulley group 1107. The first fixed frame 1101 is fixedly connected between the right sides of the tripod 1, and the first roller 1103 is symmetrically rotatably provided on the right side of the first fixed frame 1101. The second fixed frame 1104 is welded to the front side of the right part of the feed box 2. The motor 1105 is fixedly connected to the upper right part of the second fixed frame 1104, and the second roller 1106 is rotatably provided on the output shaft of the motor 1105. The second roller 1106 is rotatably provided on the lower right part of the second fixed frame 1104. A pulley group 1107 is provided between the rear parts of the two second rollers 1106. The pulley group 1107 consists of two pulleys and a flat belt. The rear parts of the two second rollers 1106 are fixedly connected with pulleys, and flat belts are wound around the two pulleys.

[0035] When the device is to be used, the staff first takes out the fixing nail 1004, and then the staff moves the sliding sleeve 1002 left and right, and the sliding sleeve 1002 drives the baffle 1001 to move left and right, thereby adjusting the cutting length of the welding rod. When the position adjustment of the baffle 1001 is completed, the staff inserts the fixing nail 1004 between the first positioning hole 1003 and the second positioning hole 1005, thereby fixing the position of the baffle 1001. Then the staff turns on the motor 1105, and the output shaft of the motor 1105 drives the second roller 1106 to rotate. The second roller 1106 drives another second roller 1106 to rotate through the pulley set 1107. Then the staff extends the welding rod between the two first rollers 1103, causing the two first rollers 1103 to rotate, thereby assisting the welding rod to move to the left. When the welding rod contacts the two second rollers 1106, the two second rollers 1106 drive the welding rod to move to the left. The welding rod is moved into the feed box 2. When the welding rod moves to the left and contacts the baffle 1001, the staff turns off the motor 1105, thereby stopping the second roller 1106 from pushing the welding rod. The staff then presses the handle 7 downward, and the handle 7 drives the T-shaped slide bar 5 to move downward. The first elastic member 9 is stretched accordingly, and the T-shaped slide bar 5 moves downward, driving the cutting knife 6 to move downward. The cutting knife 6 moves downward to cut the welding rod. The staff then releases the handle 7, and the first elastic member 9 is reset, driving the T-shaped slide bar 5, the cutting knife 6 and the handle 7 to move upward and reset. The staff then takes out the cut welding rod, and turns on the motor 1105 again, thereby causing the two second rollers 1106 to push the welding rod to the left and contact the baffle 1001. The above operation is repeated, and the welding rod can be cut off at equal intervals. When the device is not needed, the staff turns off the motor 1105 and takes out the excess welding rods.

[0036] Example 2

[0037] Based on Example 1, see Figure 1 and Figure 6 As shown, it also includes a clamping mechanism 12, the clamping mechanism 12 includes a second slide rail 1201, a second fixed plate 1202 and a second elastic member 1203, the second slide rails 1201 are fixed on both sides of the front and rear sides of the upper middle position of the base 3, and a second fixed plate 1202 is slidingly arranged between the two second slide rails 1201. The right side of the second fixed bottom is an inclined surface, and a second elastic member 1203 is connected between the lower part of the second slide rail 1201 and the second fixed plate 1202.

[0038] See Figure 1 、 Figure 8 and Figure 9As shown, it also includes a prying mechanism 14, which includes a pressure rod 1401, a third fixing frame 1402, a fixing rod 1403, a third elastic member 1404, a fourth fixing frame 1405 and a top plate 1406. The front and rear sides of the upper part of the T-shaped slide bar 5 are fixed with a pressure rod 1401, and a third fixing frame 1402 is provided on the left side of the top of the base 3 by welding. The fixing rod 1403 is rotatably provided on the third fixing frame 1402. A third elastic member 1404 is connected between the middle position of the top of the base 3 and the fixing rod 1403. The right end of the fixing rod 1403 is fixed with the fourth fixing frame 1405. The pressure rod 1401 moves downward and contacts with the fourth fixing frame 1405. The left end of the fixing rod 1403 is fixed with a top plate 1406, and the top plate 1406 is stuck in the left part of the base 3.

[0039] When the welding rod is pushed to the left by the second roller 1106 and contacts the inclined surface on the right side of the bottom of the second fixed plate 1202, the welding rod squeezes the second fixed plate 1202 and moves upward, and the second elastic member 1203 is stretched accordingly, so that the second fixed plate 1202 clamps the welding rod. When the welding rod contacts the baffle 1001, the staff presses the handle 7 downward, and the handle 7 drives the T-shaped slide bar 5 and the cutting knife 6 to move downward, and the first elastic member 9 is stretched accordingly, so that the cutting knife 6 cuts the welding rod. The T-shaped slide bar 5 moves downward and drives the pressure rod 1401 to move downward. When the pressure rod 1401 contacts the fourth fixed frame 1405, the pressure rod 1401 squeezes the fourth fixed frame 1405 to rotate, and the third elastic member 14 04 is then stretched, and the fourth fixing frame 1405 rotates to drive the top plate 1406 to move upward and separate from the base 3, so that the welding rod is pushed upward by the top plate 1406, and the second fixing plate 1202 is squeezed and moved upward, so that the second elastic member 1203 is stretched again, and then the staff takes out the top plate 1406, and the second elastic member 1203 is reset, driving the second fixing plate 1202 to move downward and reset. At the same time, the staff releases the handle 7, and the first elastic member 9 is reset, driving the T-shaped slide bar 5, the cutting knife 6 and the handle 7 to move upward and reset. In this way, the pressure rod 1401 cooperates with the fixing rod 1403, so that the top plate 1406 can push the welding rod upward, making it convenient for the staff to take out the welding rod.

[0040] See Figure 1 、 Figure 10 and Figure 11As shown, it also includes a limiting mechanism 15, which includes a fifth fixed frame 1501, a sliding member 1502 and a fourth elastic member 1503. The fifth fixed frame 1501 is fixed on both the left and right sides of the upper part of the first slide rail 4. The sliding member 1502 is slidably arranged on the fifth fixed frame 1501. The T-shaped slide bar 5 is in contact with the sliding member 1502. The fourth elastic member 1503 is connected between the sliding member 1502 and the fifth fixed frame 1501. The fourth elastic member 1503 is sleeved on the sliding member 1502. The facing sides of the adjacent sliding members 1502 are both arc surfaces, so that the T-shaped slide bar 5 can better squeeze the sliding member 1502 to move outward.

[0041] See Figure 1 and Figure 7 As shown, it also includes a protective mechanism 13, which includes a protective plate 1301 and a fixed block 1302. The fixed block 1302 is embedded in the outer upper part of the first slide rail 4 on the front side, and the fixed block 1302 is embedded in the outer upper part of the first slide rail 4 on the rear side. The protective plate 1301 is fixed to the bottom of the fixed block 1302.

[0042] Initially, the sliding member 1502 is in contact with the T-shaped sliding bar 5. When the staff presses the handle 7 downward, the handle 7 drives the T-shaped sliding bar 5 and the cutting knife 6 to move downward, and the first elastic member 9 is stretched accordingly. The T-shaped sliding bar 5 moves downward to squeeze the sliding member 1502 to move outward, and the fourth elastic member 1503 is compressed accordingly. When the T-shaped sliding bar 5 is out of contact with the sliding member 1502, the fourth elastic member 1503 is reset to drive the sliding member 1502 to move inward and reset. The T-shaped sliding bar 5 drives the cutting knife 6 to continue to move downward to cut the welding rod. When the welding rod is cut, the staff releases the handle 7, and the first elastic member 9 is compressed accordingly. 9 reset drives the T-shaped slide bar 5, the cutting knife 6 and the handle 7 to move upward. When the T-shaped slide bar 5 moves upward and contacts the sliding member 1502, the T-shaped slide bar 5 squeezes the sliding member 1502 to move outward, and the fourth elastic member 1503 is compressed accordingly. When the T-shaped slide bar 5 is out of contact with the sliding member 1502, the fourth elastic member 1503 resets and drives the sliding member 1502 to move inward and reset. In this way, the T-shaped slide bar 5 is supported by the sliding member 1502, thereby preventing the T-shaped slide bar 5 from driving the cutting knife 6 to move downward easily. The protective plate 1301 can play a protective role to prevent the staff from accidentally touching the cutting knife 6.
