Detailed Description
The invention is further described with reference to the drawings and the detailed description.
For convenience of description, one end of the handle 7 is set to be in a rear direction, and the other end opposite to the handle 7 is set to be in a front direction.
As shown in fig. 1 to 3, the present invention includes a bottom plate 9, an upper plate 3, a sliding seat 11, and a pressing plate 6.
The left side and the right side of the front end of the bottom plate 9 are respectively provided with a vertical rod 1, and the front end of the upper plate 3 is positioned between the two vertical rods and is hinged with the two vertical rods 1. In the optimized scheme, a plurality of hinge points 3 hinged with the front end of an upper plate 3 are respectively arranged on the inner side surfaces of two vertical rods 1, a pin is respectively fixedly arranged on the left side and the right side of the front end of the upper plate 3, and the hinge points 3 are holes or grooves and can enable the pins to be inserted into the holes or grooves. The hinge points 3 are vertically arranged, a vertical slideway is arranged on the front side or the rear side of each hinge point 3 and is connected with each hinge point 3, the slideway is a groove or a strip-shaped hole, the pin can slide up and down in the slideway, and the connection mode of the slideway and the hinge points 3 is also a groove or hole mode, so that the pin can slide from one hinge point 3 to the other hinge point 3, thereby playing the role of changing the height of the hinge position. Thereby being well suitable for samples with different sizes. The rear ends of the bottom plate 9 and the upper plate 3 are respectively fixedly provided with a handle 7 so as to be convenient for holding and pressing by hands.
The upper surface of the bottom plate 9 is provided with a sliding groove 10 moving along the front-back direction, and the lower end of the sliding seat 11 is in a shape matched with the sliding groove 10, so that the sliding seat 11 can slide back and forth on the bottom plate 9 along the sliding groove 10. An extension spring 12 is arranged between the sliding seat 11 and the front end of the bottom plate 9. As shown in fig. 3, the sliding seat 11 is a U-shaped structure, and includes a horizontal plate and two vertical plates 4, and the lower ends of the two vertical plates 4 are fixed on the edges of the left and right sides of the horizontal plate. The pressing plate 6 is positioned between the two vertical plates 4 of the sliding seat 11, the left side and the right side of the pressing plate 6 are respectively provided with a vertical side wall 5, and the lower ends of the side walls 5 are fixed on the edges of the left side and the right side of the pressing plate 6. A series of ratchets which are matched with each other are respectively arranged on the inner side surface of the vertical plate 4 of the sliding seat 11 and the outer side surface of the pressure plate side wall 5, and the direction of the ratchets can only enable the pressure plate side wall 5 to move downwards in a single direction. Wherein the ratchet of the lateral wall 5 of the pressing plate is positioned at the middle upper part or the middle part of the outer lateral surface of the lateral wall 5 of the pressing plate, and the lateral wall 5 of the pressing plate is made of elastic material, namely when the lateral wall 5 of the pressing plate is pinched inwards by hands, the ratchet on the lateral wall 5 of the pressing plate and the ratchet on the vertical plate 4 of the sliding seat can be separated from each other, so that the pressing plate can move upwards freely. The width of the vertical plate 4 of the sliding seat is larger than that of the side wall 5 of the pressing plate, inner flanges 13 protruding towards the inner side direction (namely towards the direction of the pressing plate 6) are respectively arranged on the two side edges of the inner side surface of the vertical plate 4 of the sliding seat, and the position of the side wall 5 of the pressing plate is limited through the action of the two inner flanges 13, so that the vertical plate can only move along the vertical direction and cannot move back and forth.
The middle position of the upper plate 3 passes through the space between the two side walls 5 of the pressing plate 6, and the upper surface of the horizontal plate of the pressing plate 6 is an arc-shaped surface with a high middle part and low front and back sides, so that the upper plate 3 can be pressed at the position close to the middle of the horizontal plate of the pressing plate 6 instead of the front edge or the back edge. The upper surface of the horizontal plate of the pressure plate 6 and the lower surface of the upper plate 3 are respectively provided with a series of transverse stripes to prevent slipping. A compression spring 8 is arranged between the bottom plate 9 and the upper plate 3, and the upward elastic force of the upper plate 3 is given by the compression spring 8.
The operation flow is as follows: before use, the hinged position between the upper plate 3 and the bottom plate 9 is set according to the size of a sample, so that the upper plate 3 is kept low in the front and high in the back, the distance between the two handles 7 is convenient to grasp, the sample can be pinched and broken when the upper plate 3 is basically horizontal at the left and right or at the high position in the front and low back, and then the sample is placed below the upper pressure plate 6 of the sliding seat 11. The slide seat 11 can be selectively prevented from being at different positions according to the hardness of the sample, and can be properly placed forwards to obtain larger pressure if the hardness of the sample is larger; if the sample is less hard, it may be placed backwards to obtain a larger stroke, and if the platen stroke is too small, it may be possible to simply crush the sharp corners of the sample ends, but not the whole. When the sample is not very hard, the handle 7 can be directly clamped and crushed by holding; when the sample is very hard, the sample cannot be crushed at once, and the pressure plate 6 can be pressed downwards by a certain amplitude when the handle 7 is held down for the first time, so that the sample is clamped and the sharp corner at the end part of the sample is crushed; then the handle 7 is loosened, the upper plate 3 is bounced upwards for a certain distance through the compression spring 8, a certain gap is formed between the upper plate 3 and the pressing plate 6, so that the sliding seat 11 can be pulled forwards for a certain distance through the action of the extension spring 12, the pressing plate 6 is propped against the upper plate 3 again, and then the handle 7 is held down again, so that the sample can be crushed. At this moment, because the sliding seat 11 moves forward for a certain distance, the upper plate 3 is actually in a lever structure, and the resistance arm is reduced after the sliding seat 11 moves forward, so that the lever structure is more labor-saving, and a sample can be easily clamped and crushed when the lever structure is pressed for the second time.
The device is a labor-saving lever structure, and when a sample is not very hard, the sample can be clamped and crushed at one time; when the sample is hard, the sample can be clamped and crushed by reducing the resistance arm, but the motion amplitude of the handle 7 can be increased while reducing the resistance arm, namely the opening angle of the handle 7 is too large, the operation is inconvenient, and the sample is clamped and crushed twice; resistance arm is great relatively when first time to can obtain great stroke, make it walk too much stroke when the resistance is not very big, because resistance grow this moment when walking back little half stroke, consequently accomplish last clamp garrulous process through the mode that reduces resistance arm, thereby keep comparatively comfortable holding in whole clamp garrulous process and feel, especially need carry out a large amount of samples and press from both sides garrulous during operation, be difficult to fatigue. The following operations can be performed in the actual use process: the sample is put, is got to the left hand, and handle 7 is held to right hand one hand, through both hands cooperation operation, makes whole process of opening the sample very high-efficient, convenient, is particularly suitable for large batch sample to press from both sides garrulous work.
It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
