Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure of the present invention.

It will be understood that when an element is referred to as being "secured to," "disposed on," or "mounted to" another element, it can be directly on the other element or be indirectly on the other element. One element is said to be "connected," "connected," and "fixedly connected" to another element, either directly or indirectly connected to the other element. In addition, attachment is generally referred to as attachment, where attachment may be by any means conventional in the art, such as "threading," "riveting," "welding," or the like.

As shown in fig. 1-5, a handheld portable clamp comprises a handle 1 and a clamping member 3, wherein the clamping member 3 is a cross-shaped structure formed by fixedly butting the end portions of two first clamping bars 34 and two second clamping bars 35, the tail end of each second clamping bar 35 is fixedly connected with a fixed clamping jaw 36, and the tail end of each first clamping bar 34 is connected with a movable clamping jaw 37 through a sliding rod 32; that is, there are four jaws, two fixed jaws and two movable jaws, and the two fixed jaws 36 may be disposed adjacently or disposed at an interval. They are butted in a cruciform configuration to improve stability and balance when clamping a workpiece.

One end of the sliding rod 32 is embedded in the first clamping rod 34 and moves in a freely telescopic manner, and the other end of the sliding rod is fixedly connected with the movable clamping jaw 37; a latch type clamp 31 is connected between the slide bar 32 and the first clamping bar 34. Specifically, the fixed seat of the latch type clamp 31 is fixedly installed on the sliding rod 32, and the ferrule of the latch type clamp 31 is sleeved on the pin head fixed on the first clamping rod 34. When the handle of the latch type clamp 31 is pressed downwards, the sleeve is connected to the pin head, so that the slide bar 32 is driven to move towards the inside of the first clamping bar 34, and the movable clamping jaw 37 moves towards the inner side immediately. The workpiece to be clamped is placed between the fixed clamping jaw 36 and the movable clamping jaw 37, and the movable clamping jaw 37 moves inwards to clamp the workpiece. The latch-type clamps are commercially available for immediate use in this application.

Similarly, the latch type clamp 31 can be installed in reverse, that is, the fixing seat of the latch type clamp 31 is fixedly installed on the first clamping bar 34, the pin head is fixed on the sliding bar 32, and the ferrule of the latch type clamp 31 is sleeved on the pin head. Similarly, when the handle of the latch type clamp 31 is pressed downward, the slide bar 32 carries the movable jaw 37 toward the inside of the first clamping bar 34, and the workpiece is clamped.

In order to further reinforce the clamping force of the movable clamping jaw 37, a waist-shaped hole 341 is formed in the side wall of the first clamping bar 34, and a fixing member 33 is installed on the waist-shaped hole to lock and connect the first clamping bar 34 and the sliding bar 32. The mounting is the bolt in this application optional, passes waist shape hole and the bolt hole of slide bar 32 on the first clamping bar 34 in proper order through the bolt promptly, locks both, has avoided the not hard up of bolt formula clamp 31 and has leaded to the slide bar 32 to move outward, loses the clamping-force to the work piece. I.e. initially the handle of the latch bolt clamp 31 is raised and the ferrule and pin head are relaxed as shown in figure 4. A workpiece to be clamped is placed between the fixed clamping jaw 36 and the movable clamping jaw 37, the handle of the latch type clamp 31 is pressed down, the movable clamping jaw 37 is driven to move towards the inside of the first clamping rod 34 to clamp the workpiece, then the handle of the latch type clamp 31 is buckled, and meanwhile the first clamping rod 34 and the sliding rod 32 are locked by using bolts (the state is shown in fig. 5). The slotted hole 341 on the first clamping bar 34 is for facilitating alignment with the bolt hole on the sliding bar 32, and also for fine adjustment of the bolt position.

As shown in fig. 1, 2 and 3, the handle 1 and the clamping member 3 are fixedly connected through a connecting member 2, wherein the connecting member 2 comprises a movable rod 21 fixedly connected with the handle 1 and a fixed rod 22 fixedly connected with the clamping member 3; the top end of the fixed rod 22 is embedded in the middle cavity of the movable rod 21, and the movable rod 21 moves along the fixed rod 22; the bottom end of the fixed rod 22 is welded or bolted to the center of a cross-shaped structure formed by fixedly butting the ends of the two first clamping rods 34 and the two second clamping rods 35. The side wall of the fixed rod 22 is provided with inner mounting holes at intervals in the vertical direction, the bottom end of the movable rod 21 is provided with at least one outer mounting hole, and the movable rod and the fixed rod are locked after the movable rod passes through the outer mounting hole and the inner mounting hole through a pin shaft. The height of the connecting piece 2 can be adjusted according to actual operation conditions, so that the clamp is convenient to operate by people. During adjustment, the pin shaft can be taken down, then the position of the movable rod 21 on the fixed rod 22 is moved, and then the pin shaft is inserted to lock the movable rod and the fixed rod.

Further scheme, handle 1 includes connecting handle 11 and handle 12, handle 12 has two, and the symmetry is fixed at connecting handle 11 both ends, the length of connecting handle 11 is greater than the external dimension of holder 3, also is greater than the work piece size of treating the centre gripping to can ensure in operating condition, even just take place the anchor clamps inefficacy condition, the work piece drops and also can not appear personnel injured's condition.

When the clamp is used, the height of the connecting piece 2 is adjusted, then the whole clamp is lifted and placed above a workpiece to be clamped, the latch type clamp 31 is loosened, the clamping sleeve and the pin head are in a loose state, namely, the movable clamping jaw 37 is adjusted to be positioned at the farthest position, so that the four clamping jaws are positioned outside the workpiece and tightly attached to the inner side wall of the fixed clamping jaw; finally, the handle on the latch type clamp 31 is pressed, the sliding rod 32 is pulled to drive the movable clamping jaw 37 to move towards the inside of the first clamping rod 34 together, so that after the workpiece is clamped, the handle of the latch type clamp 31 is buckled, and then the first clamping rod 34 and the sliding rod 32 are locked by using bolts (the state is shown in fig. 5). At this time, the work can be normally carried out, two workers hold the handle 12 to lift the whole body from the ground to a predetermined position, release the latch type clamp after reaching the desired position, separate the clamp from the work, and then end the carrying process.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
