In the conventional structure, when the blade is extended out of the casing, the positioning function of the steering mechanism causes the blade to no longer move until the remaining function is released. The most common structure is shown in the figure. The outer casing 91 houses a blade 9 2 and controls the slip of the blade 92 by a steering mechanism 9 3 connected at the end of the blade 9 2 . The rear opening of the outer casing 91 is covered by a removable cover member 94. Referring to the first and second figures, the steering mechanism 9 3 has a slider 9 3 i which is disposed inside the outer casing 91 to slide. The rear edge of the slider 9 3 向上 protrudes upwards - for the elastic strip 9 3 2, the end of the elastic strip 9 3 2 forms a limiting block 9 3 3 'the limiting block 9 3 3 and the recording rack 9 1 1 of the outer casing 91 The interference is formed to form a positioning action, and the _ fixed push block 9 3 4 is provided with a sliding push block 9 3 5 , and the bottom surface of the sliding push block 9 3 5 is provided with a control block 9 36. When the sliding push block 9 3 5 is connected to the fixed pushing block 9 3 4, as shown in the first, the operating block 9 3 6 is relatively far away from the limiting block 9 3 3, so that the elastic card bar 9 3 2 can swing freely, so that the operating mechanism 9 3 The blade 92 can be displaced within the outer casing 91. When the sliding push block 9 3 5 is away from the fixed minus 9 3 4, as in the first B riding, the control block 9 3 6 is just positioned between the 3 M393402 two limit blocks 9 3 3, so that the elastic card strip 9 3 2 It is not possible to free the crane, __ mechanism 9 3 can not push the blade 9 2 displacement in the outer casing 9 1 , and the blade 9 2 which is pushed out of the outer casing 9 is used in order to avoid danger due to the movement of the blade 9 during use. However, the design of the prior art, since the control block 936 is always located between the elastic strips 9 3 2 'even if the sliding push block 9 3 5 is pushed closer to the nearest push block 9 3 4, the control block 9 3 6 It is still located between the two card strips 9 3 2, so that the space in which the jam card strips 9 3 2 can swing freely is small, that is, the blade 9 2 pushes the displacement, which requires a large force to cause a problem of unsatisfactory pushing. In particular, when the blade 92 is pushed, since the manipulation block 963 is still positioned between the two elastic strips 9 3 2, the miscellaneous clips 9 3 2 are broken, which affects the service life and needs to be improved. '[New content] Because of this, in order to understand the shortcomings of the structure, this creation provides a kind of front and rear pressing control device, including: The external government has a _ knife groove for the long strip, and the front end of the sipe has a front opening 'The rear end has a rear opening σ' and the rear opening is covered with a removable cover element; and a top surface is formed inwardly from the rear end edge, at least partially formed at both edges of the guide groove a pair of serrations; a blade disposed in the slot of the housing in the direction of the slot and having a circular hole near the rear end; and a pressing mechanism for sliding in the slot direction The guide groove 4 M393402 is disposed in the casing, and has a slider disposed in the slot, and a pressing block disposed above the guiding slot; the top surface of the slider has a bump near the leading edge.
